2090487 9203587 PCTABS00011 The present invention is designed to improve a method of deposition of coatings upon a metal or alloy substrate. The coating comprises aluminum or aluminide material interdiffused with a transition metal deposited by chemical vapor deposition which utilizes organometallic precursors to facilitate the deposition of the transition metal. The improvement permits better control of the process and permits coating of complex substrates including those with internal passages or holes. In the embodiment involving a first deposition of aluminum or aluminide coating, applicants have achieved deposition thereon of the transition metal. Platinum is the preferred transition metal to be used in the subject method. A product is taught. This product can be a component from a gas turbine engine.
