Abstract

A study has been made on surface mechanical properties of Ti+-implanted Fe-Cr alloys with various Cr concentrations. The implantation was performed in the dose range from 1 × 1016 to 3×1017 Ti+/cm2 at the energy of 150keV. As the Cr concentration becomes lower, the friction coefficient of implanted alloys decreases, although the increase in the surface hardness is not obvious. XPS spectra show that the implantation caused the invation of carbon to form Fe-Cr-Ti-C metastable alloys containing chromium and iron carbides. It is concluded that Ti +-implantation is useful for decrease in friction of Fe-Cr alloys with the lower Cr concentration.
