ABSTRACT:
A method for treating orthopedic implants subject to wear and fatigue, and an orthopedic implant device treated in accordance with the described method. The orthopedic implant device is initially located in a reaction vessel. The outer surface of the orthopedic implant device is then subject to plasma nitriding so as to form a nitrogen enriched layer on the outer surface of the orthopedic implant device.
