Sažetak

The aim of this masters thesis “Evaluation of corrosion protection properties of organic coatings on different metal substrates” is to examine the corrosion resistance properties of various CED and powder coatings, commonly utilized in the automotive industry. For this purpose, standardized steel, hot-dip galvanized steel and aluminium specimens are coated and subsequently tested in accelerated corrosion tests, the emphasis being on the climatic test according to VDA 233-102. The protective properties of the coatings are additionally studied using DC and AC electrochemical methods.
The main evaluation criteria are degree of rusting on surface and edges, degree of corrosion and delamination around a scribe, degree of blistering, cross cut test and Daimler scratch test. The utilized accelerated corrosion tests exhibit apparent differences in the onset and character of corrosion regarding those evaluation criteria. Key influencing factors for corrosion resistance, like coating thickness and pre-treatment methods are determined.
