Abstract:

Two symmetric Polaris nozzles were coated with niobium carbide during the investigation of the carbide coating of full scale nozzles. A concentrated effort was made to eliminate non-uniformity of deposits and the non-reproducibility of deposition rates due to growth formations on injector tips. An injector evaluation study has resulted in improved injector performance. One hafnium carbide coated nozzle was fired for evaluation the coating failed in five seconds. Author
