The possibility of wear control in Metal-on-Metal artificial joints has been investigated by using a uni-directional sliding tester and a reciprocating pin-on-plate tester. The mechanism to reduce the amount of wear was the promotion of oxidization of bearing surfaces by means of externally applied magnetic field. Bearing materials were austenitic stainless steel (SUS304, SUS316) which are paramagnetic materials. In uni-directional wear tests of SUS304 sliding on SUS304 and SUS316 on SUS316 in atmosphere of air, the reduction in the amount of wear was observed by means of magnetic filed, if the influence of the magnetic field horizontal to the surfaces, which enhances wear rate, could be avoidable. The magnetic field, however, deteriorated the wear characteristic or obstructed the severe to mild transition in the tests where sliding materials were SUS304 on SUS316 and SUS316 on SUS304. The influence of magnetic field, which reduces the amount of wear of SUS316 on SUS316, was confirmed in water-based lubrication (distilled water, saline solution with and without proteins) and reciprocated sliding. The influences of magnetic field were varied by the constituents of lubricant (chlorine ion, proteins).
