Abstract
Surface mechanical strength of chromium base (electrolytic and plasma sprayed) coatings is studied for friction and wear applications in nuclear environment. Indentation, scratch, and wear testing results are compared. In particular intrinsic coating brittleness is investigated as a mechanism responsible for impact wear. Electrolytic, hard chromium plate has a wear resistance well below that of the spray coated specimens studied. Acoustic emission level and brittle damage features are shown to be correlated.
