Development and Evaluation of PG/SiC Codeposited Coatings for Rocket Nozzle Inserts. Volume II. Vapor Deposition of Pyrolytic Graphite/Silicon Carbide Codeposited Coatings

Abstract

Parameters were established to vapor deposit PG/SiC coatings on nozzle components with throat diameters up to 1.7 inches. The coatings were deposited from dilute methane and methyltrichlorosilane in rapidly flowing nitrogen at atmospheric pressure. The coatings were characterized with respect to morphology and SiC content. Coated throat liner components for 1.0-inch throat diameter subscale test nozzles and for 1.7-inch throat diameter HIPPO test nozzles were fabricated.
