Abstract

An experimental study was performed to investigate the effect of atomic attrition on wear behavior of AISI D2 steel. Wear tests were conducted under three different loads (5, 10, and 20 N) and sliding speeds (100, 200, and 500 rpm), using ball-on-disk type tester and SiC ball. After wear test, the specimen nitrided with ion bombardment showed superior wear behavior. The enhanced hardness by ion bombardment could have a beneficial effect on increased wear resistance. In addition, a wider and more adhesive oxide layer formed on the worn surface of ion-bombarded specimen, because of the rougher structure on the surface by ion bombardment, could lead the surface to withstand wear for longer duration time, acting as a protective layer.
