ABSTRACT:
A process for producing high temperature, oxidation resistant silver metal oatings on carbon/carbon composite structures by coating the carbon/carbon surfaces with molten AgNO.sub.3 at a temperature above the melting point of AgNO.sub.3 but below the decomposition temperature of AgNO.sub.3, and then heating the resulting uniform coating of molten AgNO.sub.3 at a temperature of from the decomposition temperature of AgNO.sub.3 to about 700.degree. C. to decompose the molten AgNO.sub.3 and form a uniform coating of silver metal.
