Effects of ion implantation on friction and wear of stainless steels. [15-5PH]
Friction and wear of 304, 15-5 PH and 440C stainless steels and of pure Fe are shown to be reduced by ion implantation of Ti and C. Mechanically polished samples were ion implanted to fluences of 2 x 10/sup 15/ Ti/mm/sup 2/ (90 to 180 keV) and 2 x 10/sup 15/ C/mm/sup 2/ (30 keV); the implantation profiles of the two elements extended to approx. 0.1 ..mu..m and approximately overlapped each other. The effects of normal load (Hertzian stresses in the range of 690 to 1840 MPa) on friction and wear were evaluated in the pin-on-disc configuration with no lubrication. 304 pins were used and are shown to give results similar to those previously reported for 440C pins. Ion implantation reduces friction coefficients by up to 80% and decreases the maximum wear depths by up to 95%, but the magnitude of reductions depends on the material and the load conditions. Transfer of material containing Ti from the implanted plates to both 304 and 440C pins was observed. A change in wear mechanism was detected in the wear tracks as the load was increased: fine-scale abrasive-type parallel grooves were present at light loads while galling was observed at high loads. 6 figures.
