Summary
Lectures include surface treatment and coatings applied in the automotive industry. They include the basic physical, mechanical and chemical properties of layers and coatings, explain their concepts, advantages and disadvantages, the quality assessment and the durability of these coatings. In the subject are presented the main pretreatments and technologies of surface treatment: electrolytic (galvanic) deposition, application of coating systems (including cataphoresis) for corrosion protection. Layer technology with increased wear resistance and other degradation processes. Testing methods for determination of surface and coating properties, mainly the surface composition and structure, roughness, the adhesion and thickness of the coatings.
