Abstract
A comparison has been made of the long term stability and corrosion re sistance of trivalent chromium deposited from a chloride based solutio n and hexavalent chromium deposited from a sulphate based solution. Th e work showed a difference in corrosion resistance between the two sys tems and has revealed the corrosion mechanism that caused the failure of the plated films. All the work was carried out on a brass substrate overplated with bright nickel to provide a substrate for the chromium deposit.
