TOP 8 means of protecting metal from corrosion: which one is better to choose and rating of the best

Corrosion also causes many problems in construction. Metal buildings, garages, hangars, etc., fences, load-bearing parts of frame structures, and roofing suffer. This “ruthless enemy” does not spare plumbing and household appliances, especially those in contact with water.

Corrosion processes are not easy to deal with, but it is still possible and definitely necessary to fight. And it is very good that man has created special “weapons” for these purposes - I mean a fairly wide range of different means. These are what we will talk about: means of protecting metals from corrosion - types, methods of application, rating of the most effective compositions.

Ways to combat corrosion

Metal corrosion is a destructive, lattice-destroying, redox chemical process. It is most often caused by the high chemical activity of the metals themselves - many remember from the school chemistry course the “line” of the activity of elements. It can be activated when unfavorable conditions are created, for example, high humidity and low temperatures, in an aggressive salt, acidic or alkaline environment.

Most often we have to deal with corrosion of ferrous metals, that is, various types of steel and cast iron, used literally everywhere, in all spheres of human activity. The process begins to reveal itself by the appearance of red stains or stains on the metal surface.

If corrosion is not dealt with, it can show its extremely destructive power - metal products quickly become unusable.

If no steps are taken, the outbreak begins to grow, capturing more and more areas. And sometimes this happens unnoticed. Thus, many areas of mechanisms, instruments, etc. - are simply hidden from view, and can only be seen when the unit or entire device is completely disassembled. And other pockets of corrosion may be hidden under a layer of paint for the time being, and only when the process has gone very far - first appear in the form of swellings, and then as rust breaks out.

Some owners try to deal with identified pockets of corrosion mechanically. That is, by grinding the damaged area with sandpaper or special discs, reaching the “healthy” metal.

However, such a technique, if it can be applied, should be done with extreme caution, and only as a preliminary step, before applying special compounds. Only mechanical cleaning is a very ineffective means.

Spot corrosion showing through the paint layer

It is especially difficult to remove small pinpoint rust using this method, since during the cleaning process they become clogged with finely dispersed corrosive dust, and they become practically invisible. But the trouble is that they don’t go away, and will definitely show themselves in the future, even after coloring. Therefore, chemical treatment is more reliable.

In addition, if thin metal is affected by rust, then during cleaning, under the pressure of brushes or abrasive material, it can be damaged down to a through hole.

In this regard, it is recommended to use chemical compounds that clean the metal and prevent the occurrence of corrosion in the future. Moreover, with their help, you can even successfully deal with outbreaks in hard-to-reach areas, where you cannot reach the affected area by any other means without disassembling the mechanism.

Why does rust form?

Any environment is considered aggressive for unprotected metal. For this reason, its surface layer is constantly exposed to all sorts of chemical reactions. Subsequently, rust stains appear, the appearance of the product is lost, and its strength characteristics deteriorate.

In addition, iron devices that are constantly exposed to excessive temperatures suffer from corrosion: engine components, furnace fittings, turbine blades. Metal bases that are in prolonged contact with various liquids (water, alcohol) are also susceptible to corrosion.

Types of corrosion protection products

There are several types of compounds designed to combat corrosion. These are rust converters, special primers and anti-corrosion coatings:

• One of the most commonly used and effective products are the so-called rust converters. These compositions are capable of not only removing at the chemical level, but transforming the resulting corrosion products into a protective, fairly strong film, a kind of surface primer. Such compositions are economical in consumption and perfectly perform the functions assigned to them.

An example of a high-quality rust converter
Converters are sold in liquid form (solutions or suspensions), and you can choose the optimal form of application, depending on the location of the damaged area - whether it will be applied with a brush, or whether using a sprayer seems more convenient.

The converters are suitable for processing any metal parts, but provided that the thickness of the affected layer does not exceed 15÷20 microns. The composition will not penetrate deeper - it will simply cover the damaged area with a phosphate film, and the corrosion center remaining underneath will continue to corrode the metal.

• Metal primers are no less popular than rust converters. You can find different versions of these chemicals on sale - these are passivating, phosphating, protective, insulating, as well as transforming (that is, in many ways similar to the converters mentioned above) and others.
• Another group of materials for protecting metal from rust are special anti-corrosion coatings used in combination with the other materials mentioned above.

Types of corrosion

Corrosion has a wide distribution and a variety of conditions and environments in which it can begin. Therefore, there is no specific classification of different cases of corrosion yet.

The table shows the extensive classification of corrosion that exists today.

The huge number of types of corrosion has led to the emergence of an equally large number of methods and techniques to combat each of them. But this issue is not closed and work continues to create new methods that will be more effective.

Removing rust from metal surfaces

If we are talking about cars, then corrosion most often appears on the car body. It is clear that any car owner is interested in the “health” of his “pet”, and regular updates of anti-corrosion protection are entirely on the owner’s conscience. But it also happens that corrosion finds loopholes, or due to some circumstances, vulnerable areas appear on the protective layer.

If the slightest signs of damage are detected, it is necessary to take immediate action, otherwise the focus of active oxidation will not only expand, but also go deeper into the metal. If the metal sheet is eaten through by rust, then other, more expensive repair methods will have to be used.

Here you need to act quickly: if you come to your senses in time, you can still return the damaged area to its original appearance (provided you choose the right shade of paint).

Removing rust from a car body - applying converter with a brush

Any of the selected rust removers must be used in the prescribed sequence. Only in this case can you achieve the desired effect:

• The first step is to carefully clean the damaged area from loose rust using a wire brush and then sandpaper of the desired grain size.
• Next, the surface is treated with a rust converter;
• The next step is to wash the treated area several times (if specified in the instructions for the rust converter, since sometimes this is not required.)
• After this, the metal surface is dried with a rag or using a hair dryer;
• Once the surface is ready, they move on to painting work.

When cleaning, you may find that rust has already made a through hole in the metal. If it is very small, then you can try to seal it with putty using fiberglass. If the hole has reached a significant size, it is impossible to do without welding a patch, and this will require special equipment and, naturally, stable skills in carrying out such repair and restoration work. In order not to let things get to this point, you should carefully monitor the state of the car’s anti-corrosion protection in order to stop the onset of metal corrosion at an early stage.

Cleaning the area damaged by corrosion

Restoration of an area damaged by corrosion using a converter and soil is carried out in approximately the following sequence:

• Cleaning metal from loose layers of rust.
• Degreasing the cleaned area.
• Rust converter treatment.
• If necessary, the next step is puttying, and after it dries, sanding.
• Then the surface is degreased again.
• The next stage is the application of protective primer in one or two layers.
• Next comes two or three layers of adhesive primer;
• After this, the repaired area is painted in several layers.
• A special varnish is applied on top of the paint.

When performing all work using anti-corrosion chemicals, it is necessary to comply with safety regulations. A prerequisite is the use of protective equipment - rubber gloves, goggles and a respirator. If necessary, the metal surface surrounding the damaged area should be covered to eliminate the possibility of contact with the converter, primer, and finishing paints and varnishes.

* * * * * * *

It must be said right away that the complete restoration of a heavily damaged area with its subsequent finishing painting is a rather difficult task, and not everyone can do it. That is, if you have doubts about obtaining an acceptable result, it is better to turn to specialists. This is not cheap, and therefore the best solution is to try not to bring your equipment to a state that requires such intervention. That is, to nip the appearance and development of areas affected by corrosion, as they say, “in the bud.” There are a lot of resources for this.

Next, we will present a rating of the best compounds that can effectively combat the corrosion process that has arisen on the surface and in the hidden cavities of the car.

Quality control of work performed

The methods used to protect against metal corrosion are subject to quality control. Performed to verify previously performed production controls. Defect prevention. Development of measures to eliminate detected defects. Quality control of anti-corrosion work begins with checking the documentation. Documentation on the anti-corrosion protection facility, the materials used, and product quality certificates must be provided. Upon completion of the quality control of the work, a report is drawn up containing information about the location of the work, the state of the work performed, the materials of their grade and consumption used. Information about the organization that performed the work, and the signatures of the persons who carried out the work. The commission conducting quality control checks the following parameters:

— type of anti-corrosion coating, there should be no areas that have not been treated.

— the thickness of the coating layer is checked by measuring in various places where poor quality processing is presumably possible.

— the adhesion of the paint and varnish material to the metal surface is controlled.

Which composition is better to choose?

A large number of products from domestic and foreign manufacturers are on sale (both in hardware stores and in auto parts, auto chemicals and cosmetics stores, and in hardware stores). An interesting fact is that users especially highlight formulations made by companies in Russia and the USA. Products from many European brands also perform well.

Rust converters of various types

The quality and efficiency of the presented products have been tested by practical application - all of them, if the technology of use is followed, give the expected result. Therefore, they are readily used by both repair service workers and home craftsmen.

It is also pleasantly surprising that consumers put domestic formulations in first place. Most likely, because they were developed taking into account Russian climatic and road conditions.

How to fight rust

In practice, many proven methods are used to extend the service life of iron products. But the most effective of them is treatment with chemicals (for example, inhibitor compounds). After applying them in a thin layer, the metal surface acquires reliable protection from destruction. Such compositions are often used for prophylactic purposes. Among other highly effective methods, it is worth noting the removal of rust manually or with power tools, folk remedies, and the application of anti-corrosion substances.

Mechanical cleaning

Manual treatment of iron against corrosion involves the use of a stiff brush or coarse sandpaper. Parts can be processed wet or dry. In the first case, the sandpaper is wetted in kerosene, in the second, the rust is simply scraped off.

In addition, mechanical cleaning of rusting materials is possible using the following tools:

• Bulgarian;
• electric drill (metal brush as an attachment);
• Sander;
• sandblasting machine.

The manual method is used in small areas and allows you to clean surfaces thoroughly. Power tools significantly speed up the process, but at the same time they can damage parts. When processing them, a relatively large layer of metal is removed. A sandblasting device will help to carefully remove corrosion. It is not available to everyone due to its high cost.

When processing products with sandblasting equipment, the metal surface is not ground down; a powerful jet of sand carefully removes rust Source uis-m.ru

Now, knowing the best samples of anti-corrosion compounds, according to users, you can choose the appropriate option to complete your own task. But there is no need to reassure yourself - they say that with a good composition the result is doomed only to luck. No, without work experience it’s not at all difficult to “mess up”. Therefore, if you do not have confidence in your own abilities, it is better to contact the nearest service center and entrust this process to a qualified technician.

Causes and consequences of corrosion on metal

Under ideal conditions, any metal retains its characteristics for a long period of time. Even if the material does not contain additional impurities, the absence of external influences allows the structure to maintain strength and rigidity. In real life, such conditions are almost impossible to achieve. Corrosion processes can be caused by the following reasons:

• increased air humidity, due to which the metal is constantly subjected to significant loads and very quickly begins to oxidize;
• precipitation on an unprotected steel surface also entails the spread of corrosion centers;
• often the cause of metal oxidation is stray currents present on the surface of the product;
• An atmosphere with varying levels of chemically active elements can also cause an increase in the rate of corrosion.

At the initial stage of oxidation, bright spots become noticeable on the surface of the metal, and subsequently the metal is completely covered with rust. If you do not pay attention to such phenomena, over time, corrosion penetrates inside the product, completely destroying it.

Folk remedies

If there are no chemical compounds or it is impossible to work with them, you can try to remove rust from metal products using household chemicals and other effective solutions. Some of them you will have to prepare yourself.

Cilit

The gel is designed to remove rust in the kitchen and bathroom. It is often used to clean taps, mixers, metal appliances, and other iron products. Before using the composition, it is important to consider that it can corrode the paint.

Silite is a fast-acting product; it cannot be left on the treated surface for more than five minutes Source cdn.comfy.ua

Kerosene and paraffin

The recommended ratio of ingredients is 10:1. After connecting the components, the product must be left for 24 hours, then applied to the elements damaged by rust. After 12 hours, the treated area should be wiped with a dry cloth. This method is perfect for building materials and tools.

The specific smell of kerosene does not allow you to treat exposed surfaces covered with rust in the kitchen or bathroom Source ritualica.ru

Paints for coating metal products

Paints intended for treating metal surfaces are standard and heat-resistant. In most cases, three types of compounds are used: epoxy, acrylic and alkyd. There are also special anti-corrosion paints that have the following advantages:

• effectively protect the coating from atmospheric influences and temperature changes;
• can be easily applied with a roller, brush or spray;
• many of them are quick-drying;
• have a wide selection of colors;
• are durable.

As for the most inexpensive and accessible means, then you should pay attention to ordinary silver. This coating contains aluminum powder, which forms a protective film on the product treated with it.

Which rust converter is best to buy?

As you can see, all rust converters for cars cope with the task assigned to them to one degree or another. Some turn the damaged area into soil, others form a protective film and prevent the lesion from growing. However, the most important condition for their effective action is strict adherence to the rules for applying the drug and preparing the surface to be treated as specified by the manufacturer.

Depending on the quality of the effect and the method of application of the product, the following conclusions can be drawn:

• Many car owners consider the American-made Hi Gear aerosol to be the most effective rust converter.
• Among the domestic products, the highest quality and most effective drug is the rust converter Tsinkar.
• If you have to treat a small surface against corrosion, you should opt for Fenom FN956.
• Liquid rust converter “Khimik” is suitable for those who need a large amount of product to treat a surface significantly damaged by corrosion.
• The ability to remove rust in hard-to-reach places is guaranteed by Astrochem aerosol.
• For those who value not only quality, but also a convenient method of application, without bubbles or drips, the Permatex gel rust converter is suitable.

This rating examined the 6 best rust converters for cars, and all of them protect the vehicle from corrosion quite well. But here is the main advice that experienced mechanics give: when fighting iron oxidation, you should not delay treating the damaged surface for too long; it is better to neutralize small lesions than to restore large areas.
