In this study tribological properties of pulsed electrodeposited crack free chromium and DC electrodeposited hard chromium coatings were studied, by using a dray reciprocating pin on plate wear testing machine. The crack free coatings showed higher wear rate and coefficient of friction than the hard coatings. The wear mechanism in these coatings was mainly adhesive, while the mode of the wear in the hard coatings was mainly abrasive.
