The processes of wear and destruction concern even products from such a durable material as a metal. Therefore, the owners of the car with experience with corrosion of metal parts of the body are not known for the heal.

The change in the original characteristics of metal structures during damage to corrosive processes is extremely undesirable - after all, the body is the placement of numerous aggregates and parts, the fastening of which should be distinguished by reliability.

To ensure your car a long life requires timely adoption of measures to prevent the emergence and development of rust, because the recovery of methala is the case is quite problematic.

Metal corrosion of car, general information

The most common cause of corrosion is the electrochemical effect resulting from the effects of vapor of electrolytic solution on metal body parts that have minimal protection.

In addition, condensate can accumulate in hard-to-reach places and provide its destructive impact over a long period of time. Electrochemical corrosion is also associated with the formation of currents flowing in a metal and an electrolyte solution to form closed electrical circuits.

The state of the atmosphere is negatively affecting the state: a thin film is formed on an unprotected surface, containing chlorine and sulfur impurities, oxygen molecules condensed with moisture. It is influenced by the temperature and humidity of the environment. As a result of the effect of dry corrosion, the metal fades, but not destroyed.

A completely different picture is observed in the case of high humidity - the wet film thickens, its electrical resistance is reduced to minimum values, corrosive electrochemical processes begin.

For the start of the wet corrosion, it is enough to increase air humidity up to 70%, but it is impossible to lose sight of air pollution and standing of the metal surface of the parts. The smallest particles of solids, i.e. Dust or dirt can condense moisture, larger - it is adsorbed.

Corrosion by the nature of the defeat is divided not several species:

• spotted when the depth of the lesion is significantly inferior to the diameter of the spots
• contact, occurring at points of touches of metals with different properties
• ulcerative, at which the depth and diameter of defective areas are approximately equal
• fatigue, arising at points exposed to constant mechanical stress and the effects of aggressive media
• fitting, occurring under the layer of paintwork
• slotted, the location of which is in hard-to-reach gaps or cracks.

For car bodies are characteristic:

• slit corrosion, to detect which in the initial stages is difficult, as a result - over time there may be severe damage;
• the punch, which is manifested by poor swollen on the surface of the paint, to detect such places is sometimes difficult, but in the place of the damage can be observed quite deeply damage to the structure of the metal, up to through through.

A clocking phenomenon is the damage to the corrosion of points, in which mechanical damage to the paint, chips or micro-soles are observed, to notice corrosion in this case, in order to appear on the surface of rust.

In addition, the corrosion of the automotive body is divided into:

• cosmetic, which is easy to notic on the surface, it does not affect the performance, but eliminate the foci of such a damage should be timely.
• the penetrating, arising in places of special pollution, under the influence of moisture, notice it is more difficult, the damage caused to it can be quite serious.
• structural, which negatively affects the rigidity and strength of the entire carrier structure.

Practice shows: most often corrosion amazed:

• body contact points with overhead details
• metal edges of flanges on doors, hood, lid trunk
• places of welding seams connecting body panels
• lower parts of the door panels
• bottom body

Corrosion protection methods

Since the phenomenon occurs quite often and delivers a lot of harvest to motorists, then a lot of ways to combat it and its warning is developed.

It makes sense to consider the most effective of them.

autogrurtovka

Applied to metal surfaces as the first layer. The main task is to create a good grip between the metal and paint, the protection of the metal surface from the devastating effects of rust.

The coating created by primers is not able to completely isolate the metal surface with a wet environment, but it will help slow the corrosion processes.

phosphating

To obtain a more pronounced protective effect, it is recommended to use phosphate primers that create a durable layer of oxide film. You can apply phosphate primer by dipping parts into a special container.

ocinkovka

This type of protection has two functions:

• electrochemical
• barrier

For applying a layer of galvanizing, parts are placed in a tank with a melted zinc. As a result, a layer of ferricular alloy is formed on the parts of the body, a thickness of about 1-2 microns.

autocrats and varnishes

To the paints and varnishes for the car body requires special, they should:

• form high strength film
• resistant to abrasion
• have a high adhesion in relation to the primer
• being resistant to direct sunlight

In modern car market, high-quality paints and varnishes are presented quite wide.

Film coating

Work on the application of the protective polymer film is performed by car service masters. Film This colorless and absolutely transparent, lamination may be subject to any surface.

More efficient protection today failed.

The film application technology is quite simple, but before proceeding to sticking, it will be necessary to completely remove traces of corrosion, eliminate the chips and secure and paint the scratch.

Next, the protective layer is removed from the polymer film and it is simply pressed by sticking side to the dry and clean surface of body parts.

Such a film can serve for about three years, then it will have to be removed and in the same way to stick a new one.

And as a means of protection, it is used: bitumen mastic, liquid polymers and oils, wax and paraffin.

Rust converter from which it consists

To carry out a procedure for restoring detected rusty areas, preliminary preparation will be required, often resorted to the use of modifiers.

Converters can cope with a rust layer thickness of which does not exceed 100 microns if the corrosive layer is thicker - it is recommended to use gel compositions.

Important condition: The adhesion of the coating paintwork materials relative to the transformed layer should be high enough and exclude the possibility of an electrochemical reaction.

By chemical composition, converters are divided into:

• neutral and acidic
• multicomponent and single-component
• film-forming

As a result of their exposure, the primer layer can form, in some cases the transformed layer is removed.

The active substance of almost all rust modifiers is orthophosphoric acid. Under its impact on the surface of the metals, phosphate film is formed, characterized by protective abilities and having high adhesion relative to autocrasors and varnishes.

Orthophosphoric oxides orthophosphoric acid acts on the scale and nonhyrated oxides.

In addition to orthophosphoric acid, as part of modifiers may be attended by:

• Oxycarboxylic acid (Tannin). Among the positive properties of Tannin - the ability to inhibit influence. If plant tannins are used in the manufacture of modifiers, they are related to neutral products.
• Zinc monophosphate in combination with phosphoric acid, such a mixture is capable of forming a zinc phosphate layer capable of creating a positive electrode potential, higher than the one that is characterized by iron.
• Substances that are inhibitors of corrosion, their purpose is to slow down corrosion processes. Compositions with pronounced oxidative properties are used as passivating substances. If the metal is covered with passivating composition, the process of destruction of its corrosion slows down significantly. The purpose of adsorption inhibitors is the creation of an additional layer that enhances resistance to corrosive processes.
• In aqueous compositions, epoxy or alkyd film-forming substances may be present.

Principle of Rust Converter

The work of the rust modifier is:

• splitting rusty particles
• giving them neutrality with respect to pure metal
  The formation of a polymer-latex layer

In the resulting coating, zinc and pigments can be kept, the paint or varnish can be applied to the dry layer, the primer does not need.

Due to the simplicity of application and practicality, transforming modifiers have high demand and popularity of motorists.

The masters are more likely to resort to traditional techniques: first carefully cleaned rust, then high-quality primers are applied.

In what form manufacturers produce rust converters

The conveyor consistency can be gel, liquid, pasta-like.

It is on this factor, as well as the packaging format, it is recommended to pay attention when purchasing. If the surface area is small, then the liquid product can be purchased - it will be possible to immerse the part entirely.

For vertical surfaces, the optimal option will be using a modifier in a state of gel. If you need to apply to large areas, you should pay attention to the products, packaged in the canopy - to apply them much easier.

Before applying paint, one-component compositions are washed off, but not water, but solvents is recommended as a wash. They degrease the surface and simultaneously dried it, prepare to paint.

In what places of the body you can use rust converters

The place of using rust converter can be any metal part of the body, which has become a platform for the start of the corrosion process. The main thing is to notice in a timely manner and eliminate damage to the coating - the process of corrosion has the property to quickly distribute and capture all large areas.

Naturally, the cost of repair in case of significant corrosion damage will be considerable.

Tips of professionals

Do not fully trust advertising and believe that transducers are the means of magical, which can be used without observing the rules, treat them contaminated or raw, painted surfaces.

In fact, even high-quality funds will not be able to remove moisture and transform dirt and rust in a clean metal.

In this way, you can only hide corrosion processes, but after time the oxidation processes will again appear, even more actively.

Experts argue that proper preparation is 80% of the successful result.
