Patent number: 8790345Abstract: A prosthetic device having a generally fixed member formed from a low friction material such as ultra-high molecular weight polyethylene and an articulating titanium member, which includes an articular bearing surface. The articular surface is a zirconium oxide layer formed by applying a coating of zirconium onto the titanium member and heating this in an oxygen-containing environment. This causes the zirconium to oxidize and further causes the zirconium to migrate into the titanium member forming a titanium zirconium diffusion layer, which prevents delamination.Type: GrantFiled: August 21, 2007Date of Patent: July 29, 2014Assignee: Zimmer, Inc.Inventor: Jeffrey P. Anderson

Patent number: 8663337Abstract: A process for forming a ceramic layer comprising a compound of a metal on a deposition surface of a workpiece comprises providing a reactive gas, selecting the amounts of a vapor of the metal and ions of the metal relative to each other, generating the metal vapor, and projecting an ion beam of the metal ions. The metal vapor, the metal ions, and the reactive gas form the ceramic layer with a desired structure. The process may include the step of controlling a deposition surface temperature. In one embodiment, the metal vapor comprises zirconium vapor and the ion beam comprises zirconium ions. The relative amounts of the zirconium vapor and the zirconium ions are selected to form a zirconia ceramic layer on the deposition surface. The zirconia may have multiple crystal phases that are formed according to a predetermined ratio.Type: GrantFiled: March 6, 2012Date of Patent: March 4, 2014Assignee: Zimmer, Inc.Inventors: Jeffrey P. Anderson, Oludele O. Popoola
