Austenitic stainless steel AISI 321 is one of the most difficult-to-cut materials. In order to investigate the wear behavior of Si{sub 2}N{sub 4} ceramic when cutting the stainless steel, wear tests are carried out on a pin-on-disk tribometer, which could simulate a realistic cutting process. Test results show that the wear of Si{sub 3}N{sub 4} ceramic is mainly caused by adhesion between the rubbing surfaces and that the wear increases with load and speed. When oil is used for lubrication, the friction coefficient of the sliding pairs and the wear rate of the ceramic are reduced. A scanning electron microscope (SEM), an electron probe microanalyzer (EPMA), and an energy dispersive x-ray analyzer (EDXA) are used to examine the worn surfaces. The wear mechanisms of Si{sub 3}N{sub 4} ceramic sliding against the stainless steel are discussed in detail.
