Abstract

In chromating, conversion coatings are applied to increase the corrosion resistance, to decrease the surface liability to fingermarking, to increase the adhesion of paints or other subsequently applied coatings, and to obtain color effects. In the present work, the corrosion protection aspects of chromating are investigated by comparing treated and untreated aluminum samples using electrochemical and other techniques. The chromating solutions are based on relatively simple formulations using hexavalent chromium compounds, but with added fluoride.
