Comparison of fretting wear behavior between aluminium alloy and SUS304 stainless steel

Abstract

Fretting wear is one of the problems that influence operating lifetime of machines. In this paper, we report on the fretting wear behavior of aluminium alloy (A5056) and SUS 304 stainless steel in air and vacuum. Fretting experiments were performed using three combinations of specimens : (1) A5056 vs. A5056,(2) SUS 304 vs. SUS 304,(3) SUS 304 vs. A5056. For the combinations (1) and (2), coefficient of friction is higher in vacuum than in air. But, for the combination (3), coefficient of friction is slightly lower in vacuum than in air. And, wear volume measured shows that the combination (3) has better resistance to fretting wear.
