ABSTRACT:
A composition for use in the physicochemical surface refinement of objects having surfaces of titanium, nickel, and alloys of each, normally in a vibratory mass finishing process, comprises the combination of sulfamic acid, ammonium bifluoride, and hydrogen peroxide. The maximum concentration of the peroxide is controlled to avoid inhibiting or arresting the reaction with the metal; maintaining a minimum concentration prevents excessive metal dissolution, pitting and other undesirable surface defects.
