EVALUATION OF FATIGUE LIFE OF CHROME-ITE PLATED SPECIMENS.

Abstract

Test data are presented comparing fatigue lives of notched and unnotched aluminum alloy specimens with and without being coated by a thin electrodeposited coating called Chrome-ite. Data indicate that a substantial improvement in fatigue strength can be attained through use of Chrome-ite if cyclic stressing is confined to regions well below the proportional limit of the material. High preloads or cycling at high stresses might eliminate benefits altogether or cause detrimental effects in some cases. The fact that losses are not always accompanied by high loading indicates the need for further research on the Chrome-ite process. (Author)
