Increasing corrosion resistance of electrolytic chrome ...

Abstract. Investigations were made of the corrosion resistance and electrochemical behavior of deposits of chromium with palladium additions. It was shown that coating modification of electrolytic chromium with small additions of palladium (1 to 3 percent) can substantially increase the acid resistance of chrome coatings in solutions of nonoxidizing acids (20 percent sulfuric acid and 5 to 10 ...
