Abstract
A coated article of a stoichiometric coating composition of pyrolytic PB(Si)N on low thermal expansion carbon, graphite or ceramic materials and process of forming the coated article. The process involves introducing reactant vapors, under appropriate deposition conditions, within a heated furnace chamber containing the article to be coated. The reactant vapors are composed of ammonia, a gaseous source of boron and silicon and a diluent gas and are fed at a gas flow rate such that the combined flow rate of boron and silicon is less than the flow rate of ammonia.
