Friction and wear of stainless steels implanted with Ti and C
Friction and wear tests were completed on Fe and stainless steels of the type 304, 15-5 pH, Nitronic 60, and 440C implanted with Ti and C. Samples were mechanically polished prior to ion implantation to fluences of 2 x 10/sup 17/ Ti/cm/sup 2/ (90 to 180 keV) and 2 x 10/sup 17/ C/cm/sup 2/ (30 keV); the implantation profiles of the two elements overlapped to 0.1 ..mu..m. Light load wear conditions with no lubrication were evaluated in a pin-on-disc configuration. Ion implantation significantly reduced the friction coefficient by up to 75% and decreased the maximum wear depth by up to 95%, but both effects were material and load dependent. Only stainless steel 304 had both friction and wear reduced by implantation for all loads examined. Fine-scale parallel grooves were present in the wear track for light loads, but this wear pattern was transformed to a galled structure at high loads. A correlation existed between decreased friction, reduced wear, the wear track morphology and Ti in the wear track.
