Abstract
CORROSION of copper is inhibited in 0.1 N chromic acid of pH 1.6, a loss of 10 mg/dm2 and no change in appearance is observed after four weeks' immersion. On the other hand, corrosion is significant in sulphuric acid of this pH, and a loss of 150 mg/dm2 is recorded after an identical period of immersion. This communication describes experiments designed to obtain a fuller understanding of the mechanism by which chromate inhibits the corrosion of copper.
