<p>A composition is described 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, comprising a 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.</p> |
