PYROLYTIC CARBIDE DEVELOPMENT PROGRAM
Abstract
The processing furnace for use in coating Polaris A-3 nozzles with TaC, HfC and NbC was placed in operation. The unit performed as expected, temperature being attained with power to spare. The processing of TaC coatings on symmetric nozzles was initiated and conditions for the deposition of the stoichiometric carbide are being determined. NbC free of metal or excess C was produced as flat plate deposits. Xray analysis showed the deposits to be face centered cubic NbC with a high degree of crystal orientation. (Author)
