Abstract

Ion implantation of nitrogen and oxygen is a technique for improving the friction and wear characteristics of Co-Cr-Mo alloy used for articulation joints. This process produces lattice disorder, increases surface activity, promotes wettability and increases hardness without dimensional changes or the formation of oxides and nitrides (Cr(2)N) precipitates which could seriously decrease corrosion resistance.
