Abstract:

Investigations were made of the preparation and evaluation of refractory metal alloys of pyrolytic graphite as a function of source gas concentration, flow rate, and deposition temperature to optimize the structural performance of the products in high-temperature erosive environments. In each system analogous reaction conditions are found to be operative and microstructural, and other physical aspects similar to those of pyrolytic graphite are observed. Carbide formation and other disadvantageous aspects of the vapor deposition processes are considered. Initial studies of the materials in oxidizing atmospheres are described. Author
