ABSTRACT:
A rocket engine component is formed as a tungsten-copper composite substrate, and a functionally-gradient material coating overlying and contacting the substrate. The functionally-gradient material coating has a composition that varies nonlinearly through a thickness of the coating so as to minimize thermal stresses through the coating, and such that the functionally-gradient material coating is tungsten adjacent to the substrate and is rhenium remote from the substrate. In a preferred form, the functionally-gradient material coating includes a tungsten sublayer overlying and contacting the substrate, a tungsten-rhenium sublayer overlying and contacting the tungsten sublayer; and a rhenium sublayer overlying and contacting the tungsten-rhenium sublayer. The functionally-gradient material coating is preferably applied by a low-temperature deposition technique such as plasma enhanced chemical vapor deposition.
