Abstract
A method of providing biocompatible surface texturing on a metal component of an implantable device and the device so produced. The coating is provided by applying particles of metal falling substantially entirely in the range of 1 to 5 microns to a surface of said component to provide a layer of generally uniform thickness and sintering said particles to one another and to said component to provide a generally continuous external surface having surface texturing in the form of projections formed from said sintered particles. The particles are preferably applied to a depth of 1 to 25 microns. In a preferred embodiment particles of titanium are applied to a surface of a titanium component.
