Article having cobalt-phosphorous coating and method for heat treating

摘要

A method of processing an article having a substrate and a cobalt-phosphorous coating disposed on the substrate includes heat treating the article. At least one physical characteristic of the cobalt-phosphorous coating is altered using the heat treating to thereby change a performance characteristic of the article. For example, the article may be an actuator component having a bore or a shaft that is movably disposed at least partially within the bore.

主权项

1. A method of processing an article, comprising:
heat treating an article having a substrate and a cobalt-phosphorous coating disposed on the substrate; selecting a heat treating temperature that alters a bonding strength and maintains an initial hardness of the cobalt-phosphorous coating prior to the heat treating; and altering at least one physical characteristic of the cobalt-phosphorous coating using the heat treating to thereby change a performance characteristic of the article, wherein altering the at least one physical characteristic of the cobalt-phosphorous coating includes altering a bonding strength between the cobalt-phosphorous coating and the substrate.
