Abstract

The paper presents research determining the effect of surface preparation on the quality of varnish coatings obtained by electrophorus. The tests were carried out on steel parts used for the construction of trailers and bodies for trucks. The quality of the paint coatings obtained was determined in the corrosion resistance tests carried out using the Ascott CC1000 salt cell. The research allowed to determine the durability of the electrophoresis coating depending on the method of preparation of the surface on which they were applied. In order to supplement the tests, the thickness of the varnish coating was measured. The measurements were made by magnetic induction. In addition, roughness measurements were made to determine the effect of surface preparation on the corrosion resistance of the tested coatings. The tests were carried out before applying the coating and for the obtained varnish coat. On the basis of the presented tests, the relationship between the surface preparation method and the corrosion resistance of the tested parts was determined.
