Abstract
A method for producing a zirconia-layered orthopedic implant component includes depositing zirconium onto the orthopedic implant component, thereby forming a zirconium-layered component, and converting at least a portion of the zirconium into a substantially monoclinic zirconia surface layer unaccompanied by a substantial underlying α-phase. A method for producing a zirconia-layered orthopedic implant component includes depositing zirconium onto the orthopedic implant component by ion bombardment and deposition in a vacuum to form a zirconium-layered component including an intermix zone at least 1000 Å thick and a zirconium layer about 3-5 μm thick, and heat treating the zirconium-layered component at a temperature of about 500-600° C. in an atmosphere containing oxygen.
