Abstract : The patent describes a process for treating a titanium or titanium alloy surface to improve its bonding characteristics. It comprises directing a stream of a slurry of aluminum oxide grit in a hydrofluosilicic acid solution onto the surface for a period of time sufficient to obtain a uniform, oxide-free surface, washing the treated surface to remove grit and terminate acid reaction, and drying the treated surface. The treatment provides a chemically stable surface that is receptive to adhesives and coatings.
