Nitrogen implantation was observed to significantly improve the dry sliding properties of an ion beam mixed Fe/sub 50/Ti/sub 50/ surface alloy on AISI 304 stainless steel. Implantation to the fluence of 1.7 x 10/sup 17/ N/cm/sup 2/ at 50 keV increased the wear resistance but a decreased friction coefficient was obtained only after few hundred cycles at the beginning of the pin-on-disk test. When nitrogen was implanted to the fluence of 3 x 10/sup 17/ N/cm/sup 2/ an improved wear resistance and decreased friction were detected throughout the test of 1000 cycles. In addition, good sliding properties were also found at higher loads in the high fluence, nitrogen-implanted samples. These results differ from those obtained following a nitrogen implantation into Ti-implanted iron or iron-based alloys and are attributed to higher titanium and nitrogen concentrations.
