Abstract
A method for the protection of porous metallic surfaces, such as titanium tibial tray components, titanium hip stems, and cobalt chrome cup shells of various sizes, during machining, sandblasting, and inspection of orthopaedic implants is disclosed. The process includes the application, cross-linking, and removal of a liquid gelatin coating which provides excellent protection against dirt, dust, lint and other materials from entering the porous surfaces of the prosthetic devices during manufacturing.
