Abstract
A process for post processing a part that has a Nitinol coating applied by plasma spraying or PVD coating gives the Nitinol desirable properties of toughness and malleability. It also produces a layer of surface material that is extremely hard, chemically non-reactive, electrically and thermally insulating. The process includes selecting a part that has a surface coating of Nitinol applied by plasma spraying or PVD coating and polishing the surface coating to give it a smooth and shiny surface. The polished surface is then cleaned to remove all polishing residue. The surface of the Nitinol coating is heated a temperature in a range of about 400° C. to 900° C.; and is rapidly cooled by forced air flow over the surface coating or by low temperature air or liquid immersion. Thereafter, the outer surfaces of the layer of surface material may be repolished and reheated as before to enhance the layer of thermally produced surface material.
