Patent number: 8795441Abstract: The present invention relates to a method of reworking a composition comprising a substrate and an oxidation and/or nitridation layer on the surface of the substrate by treating the composition under reduced pressure or in an inert gas environment at an elevated temperature until the oxidation and/or nitridation layer is substantially removed from the surface. In this way, manufacturing efficiencies and yields are improved as material that would otherwise have been scrapped is now used.Type: GrantFiled: April 25, 2007Date of Patent: August 5, 2014Assignee: Smith & Nephew, Inc.Inventors: Vivek Pawar, Shilesh C. Jani, Carolyn Weaver

Patent number: 8647701Abstract: Methods of making surface hardened medical implants comprising providing a biocompatible alloy with a surface comprising an oxide or nitride layer, diffusing at least a portion of the respective oxygen or nitrogen from the oxide or nitride layer the substrate for a period of time to form a diffusion hardened zone of desired thickness. The period of time is based at least on (1) the diffusivity of a diffusing specie in the oxide or nitride layer, (2) a desired hardness profile of at least a portion of said implant defined by a function selected from the group consisting of: an error function, an exponential function, a near uniform distribution function, and any sequential combination thereof, or (3) a desired thickness of said oxide or nitride layer to be retained.Type: GrantFiled: June 27, 2011Date of Patent: February 11, 2014Assignee: Smith & Nephew, Inc.Inventors: Vivek Pawar, Shilesh C. Jani, Carolyn Weaver
