  • Development of new chemical and electrochemical procedures for the control of pretreatment sections in electrogalvanising lines of steel sheets for automotive application


In this project the test methods for measuring adhesion were described in a literature study. These included heat shock, bulge test and different pull tests. A new test method has been developed which enables the fixture of both ends of the test sample to a wheel so that the test surface is rigidly mounted. The introduction of residual stress in the surface coating due to the bending of the steel sheet will influence the absolute level of adhesion force, but as all test samples are the same thickness, the added stress will be the same in all tests. Thereby the comparability of the tests is assured.
