Abstract:

This patent discloses a process for producing high temperature, oxidation resistant silver metal coatings on carboncarbon composite structures by coating the carboncarbon surfaces with molten silver nitrate at a temperature above the melting point of AgNO3 but below the decomposition temperature of AgNO3, and then heating the resulting uniform coating of molten AgNO3 at a temperature of from the decomposition temperature of AgNO3 to about 700 C, to decompose the molten AgNO3 and form a uniform coating of silver metal.
