Abstract : Investigations were continued on the development of pyrolytic carbides specifically for application to Polaris nozzles for use with advanced propellants. Two symmetric Polaris nozzles were coated with tantalum carbide. Process parameters were investigated to determine optimum coating conditions and injector design changes were made to improve the quality of the carbide produced. Niobium carbide and tantalum carbide coated nozzles are described. Additional data for pyrolytic niobium carbide and hafnium carbide is also presented. (Author)
