Friction and Wear of Electroless Ni Based Alloy Platings under Oil Lubricating Condition

Abstract

The authors examined friction and wear characteristics of electroless Ni based alloy platings under oil lubricating condition with ring-on-disk test machine. Electroless Ni-P alloy plating, electroless Ni-B alloy plating and electroless Ni-P-B alloy plating were employed. In case of the combination of the electroless Ni-B alloy plating and the electroless Ni-P-B plating the wear occurred in the lowest contact pressure. The friction behavior was the most stable in case of the combination of the electroless Ni-B alloy plating and the electroless Ni-P alloy plating. The friction coefficient of the self-mated electroless Ni-P-B plating was small, while the wear was comparatively large.
