Abstract:
A process for imparting a uniform coating on at least a selected surface of a plurality of prosthetic components, said selected surface being less than the entire surface of each said component, the process comprising:providing a chamber having a plurality of titanium alloy evaporators disposed therein; mounting each of the said components to be coated in the chamber such that each said surface to be coated is shielded from the direct straight line-of-sight path from the most proximal titanium alloy evaporator, is oriented towards the center of said chamber, and each said surface to be coated faces at least one other surface to be coated; applying opposite charges to the titanium alloy evaporator and to each of the components to be coated for ionically bombarding the components in the chamber; and striking an arc in the chamber for ionically bombarding the components to be coated in said chamber.
