It was demonstrated that 7075-T6 and 2024-T3 aluminum treated in dilute, relatively non-toxic trivalent chromium bath have achieved salt spray corrosion resistance and paint adhesion equivalent to that of chromate conversion coatings. The trivalent chromium bath has less
tendency for inducing hydrogen embrittlement of high strength steel than a chromating ...
