Solutions against silent death from corrosion or wear and tear

Corrosion is the result of an electrochemical process that occurs with a metal simply by the presence of air or rather the moisture in that air. Surface corrosion is one of the visible consequences. Other substances such as salts and chemicals can also cause corrosion. Corrosion not only has a visual effect but can also have disastrous consequences such as the collapse of metal resulting in collapse. Even that new car would be rusted away in no time. There are also metals that undergo permanent wear and tear as a result of repetitive movement with associated friction, which can also have disastrous consequences. 

So what is the solution? 

Make everything completely in gold so that nothing can corrode? Making the complete piece in the most expensive material so that it can't wear out? No, the solution is simpler (and cheaper): apply a protective layer to the metal. Depending on the type of metal and the environment in which it will be located, different coatings can not only prevent corrosion, but can also increase the lifetime of the metal. This in turn can save high repair and replacement costs. In other words, the exterior of your new car will last longer than the engine that will drive it. But also the engine can last longer with the help of coatings, thanks to better protection against corrosion, and certainly against wear and tear caused by friction.

Many techniques available

There are an enormous number of techniques for applying coatings in all shapes and sizes. But which anti-corrosion coating applies to your specific problem? And how should this coating be applied? This mainly depends on the environment in which the metal will be located and also on the desired layer thickness of the coating. The various environments can be divided into classes. One speaks of a C1 class with a very low corrosion risk as in your home to a C5 class with a very high corrosion risk as in a chemical company where for example you work with aggressive substances. An example of an industrial capacity to protect against corrosion is an immersion painting line that uses a suspended rail system to immerse a large batch of components in the painting/coating in a continuous process (1). For protection against wear due to friction a typical example is thermal spraying. This technique also occurs in many variants such as HVOF or Plasma (2).

Finding the right partner

Of course, there are many more techniques than those mentioned here in this article. That is why it is still best to get expertise from experienced experts before making a final decision for your product, both for protection against wear and tear (2) and corrosion (3). Certainly on a large scale it is essential to be well informed about which coating and which coating technique should be used. This is in order to deliver optimal quality to your customer and also so as not to incur excessive expenses. This can save costs for both you and your customer.
