    摘要： The present invention is process for forming diffusion aluminide coatings on an uncoated surface of a substrate, without interdiffusing a sufficient amount of aluminum into a coating layer to adversely affect the coating growth potential and mechanical properties of said coating layer. A metal substrate is provided comprising an external surface and an internal passage therein defined by an internal surface, at least a portion of the external surface of the substrate being coated with a coating layer selected from the group consisting of β-NiAl-base, MCrAlX, a line-of-sight diffusion aluminide, a non-line-of-sight diffusion aluminide, a pack diffusion aluminide, and a slurry diffusion aluminide on said substrate. The external surface of the substrate is cleaned. The metal substrate is subjected to a aluminum vapor phase deposition process performed using a fluorine-containing activator selected from the group consisting of AlF3, CrF3, NH4F, and combinations thereof, at a rate in the range of about 0.036 mols of fluorine per ft3/hr of transport gas to about 0.18 mols of fluorine per ft3/hr of transport gas, at a temperature in the range of about 1350° F. (730° C.) to about 1925° F. (1050° C.), using a transport gas selected from the group consisting of argon, nitrogen, hydrogen, and combinations thereof, the transport gas being provided at a flow rate in the range of about 20 ft3/hr to about 120 ft3/hr for a period of time in the range of about 2 hours to about 10 hours. The substrate is then cooled. The present invention is also a superalloy article coated with a diffusion aluminide layer using the diffusion aluminide coating process of the present invention.

    摘要： A method for preparing a protected article includes the steps of furnishing an article to be protected, wherein the article is a component of a gas turbine engine, thereafter depositing a precious-metal-containing layer onto the article, and thereafter depositing an aluminum-containing layer by vapor-phase aluminiding onto the article overlying the precious-metal-containing layer from an aluminum vapor source that includes a fluoride. The method further includes thereafter heating the article with the aluminum-containing layer deposited thereon in an atmosphere having at least 5 percent by volume hydrogen gas, and thereafter depositing a ceramic layer overlying the aluminum-containing layer.
