Abstract
A study has been made of the frictional properties of nickel and copper implanted steel plates. Ion implantation was performed with doses of 1×1015–3×1017 ions/cm2 energies of 50–200 keV. The friction coefficients of Ni and Cu implanted specimens, measured at atmospheric room temperature with a Bowden-Leben type friction testing machine, had a tendency to increase as the total dose increased and the acceleration energy decreased. Concentration profiles were measured by secondary ion mass analysis in order to investigate the element concentration which contributes to the frictional properties. The results suggest that the amount of implanted ions remaining in the surface layer (0–400 Å) is of first importance in the frictional properties of Ni and Cu implanted steel plates.
