The wear behavior of Fe and Ni-plated Fe implanted with B, Ti or Ta ions single or dual implants has been evaluated. Friction coefficients were measured during repeated unidirectional, low speed 0.1 mmsec dry sliding of a hardened steel ball at high contract stress 0.85 GPa. In fe, the dual implants of B Ti reduced the coefficient of friction from 0.6 the nonimplanted value to 0.3 and prevented the adhesive wear damage observed on nonimplanted surfaces. Although less effective than B Ti, B Ta and B reduced the coefficient of friction initially and resisted wear better than the nonimplanted surface. In Ni-plated Fe, B implantation delayed adhesive wear and reduced the coefficient of friction from 0.5 the nonimplanted value to 0.4. Implantation of Ti and Ti B produced a higher coefficient of friction 0.6 and increased adhesive wear. Originator furnished key words include Ion implantation, Ni-plate, Friction, Wear resistance.
