Abstract

A multilayered Fe/Ti/C structure consisting of eleven alternating sublayers, four Fe, four Ti and three C, was ion mixed on an AISI 304 stainless steel substrate with 400 keV Xe2+. Complete mixing was observed after an irradiation of 1 × 1017Xe/cm2 at 550°C. Electron diffraction revealed the formation of the compounds TiC and Fe3C and a small amount of an amorphous phase. Some samples were given a second irradiation with 5 × 1015Xe/cm2 at 0°C. The phases present following the second irradiation were TiC, α-Fe and an amorphous phase. Tribological and nanoindentation measurements revealed that both types of samples possessed similar hardness and friction properties. The ion mixed samples possessed an increased hardness and a decreased friction coefficient relative to untreated polished stainless-steel substrate. However, the wear life of the hot ion mixed sample was consistently longer than the wear life of the sample processed at both 550 and 0°C. These results are explained by differences in adhesive wear which result from differences in the chemical reactivity of the phases formed during ion beam processing.
