Abstract
Orthopedic implants comprising components of zirconium or zirconium-based alloys having surfaces coated with oxidized zirconium contacting other surface-coated oxidized zirconium are disclosed. Such implants provide low friction, highly wear resistant coatings especially useful in artificial joints, such as hip joints, knee joints, elbows, etc., but also useful in non-articulating implant devices such as bone plates, bone screws, etc.
