Analysis of the Adhesion of the Surface Layer Formed due to Cataphoresis Coating

Abstract

The paper focuses on the cross-cut test, which serves as a basis for determining the adhesion test on the surface of aluminium parts. The coating adhesion test was performed according to the ISO 2409 standard where. Before carrying out the actual measurement, the tools necessary for making those individual measurements were prepared. A knife, an adhesive tape and a grid were used. The result was evaluated on the basis of the ISO 2409 standard. Spacing of a grid was 2mm apart. Grid exam cut test was carried out on 32 samples. The classification of the samples ranged from 0 to 1. At 1, we found that the surface of the material was slightly damaged. At the scale of 0, a smooth cut was made on the material surface, and no damage occurred. Through research, we found that with a constant chemical degreasing factor, the adhesion test varies according to the EN ISO 2409 standard at values 0 and 1. It follows that if we wanted to achieve worse cutting conditions in the grid, we would have to change the temperature of the solution, the time depositions.
