摘要:
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.
摘要:
The invention provides a physicochemical process for refining relatively rough metal surfaces to a condition of high smoothness and brightness, in relatively brief periods of time, which is characterized by the use of a non-abrasive, high-density burnishing media. The process can be carried out in one step and with minimal production of media fines, thus affording economic and environmental advantages.
