摘要：

Nitrogen ion implantation in titanium and Ti-6Al-4V was carried out at an acceleration voltage of 80 kV and with target temperatures between 30 and 450-degrees-C during irradiation. Ball-on-disc measurements indicated that optimum wear characteristics were obtained at the highest temperatures studied here. Rutherford backscattering and Auger electron spectroscopic surface analyses of the ion-implanted samples showed that there was a saturation dose above which no further nitrogen was retained in the material. The improved wear characteristics are attributed to precipitation of TiN, which is assumed to be promoted by the higher temperature employed. No dependence of the wear properties on the ion flux could be observed within the range of ion beam current densities studied, i.e. 1-15-mu-A cm-2.
