Abstract

A surface layer of Fe50Ti50 on AISI 304 stainless steel was produced by ion beam mixing a Fe-Ti multilayer structure. Subsequently, the layer was implanted with C, N, or C+N ions. The dry sliding properties of these surfaces were tested using a ceramic pin as a rider in pin-on-disc measurements. Implantations produced significant improvements in the surface friction and wear properties. Samples implanted with C or C+N showed good tribological properties even under conditions where the Herzian peak pressure exceeded the yield strength of the substrate. As a result of different treatments the appearance of the wear tracks examined with a scanning electron microscope was also changed.
