Abstract:
1. A simple chemical vapor deposition method for forming an aluminide coating containing at least two different extrinsic metals on a jet engine component, comprising: coupling a single port of a receptacle in fluid communication with a main reaction chamber; heating the receptacle to form a first vapor phase reactant including a first extrinsic metal that is transported without assistance of a separate flow of a carrier gas from the receptacle to the main reaction chamber; generating a second vapor phase reactant including a second extrinsic metal inside the main reaction chamber, the second extrinsic metal differing in composition from the first extrinsic metal; heating the jet engine component; and contacting the first and second vapor phase reactants with the heated jet engine component to form the aluminide layer including the first and the second extrinsic metals, wherein the aluminide layer is capable of forming a complex oxide when heated in an oxidizing environment.
