Abstract: A process for forming a coating on a surface of a substrate (14), in which the heating source for the coating process is microwave radiation (18) so that heating of the coating material is selective and sufficient to melt and bond the coating material to the substrate (14) without excessively heating the substrate (14). The process entails forming a coating material (10) containing powder particles (12) that are sufficiently small to be highly susceptible to microwave radiation (18). The coating material (10) is applied to a surface of the substrate (14) and subjected to microwave radiation (18) so that the powder particles (12) within the coating material (10) couple with the microwave radiation (18) and sufficiently melt to form a coating (28) on the substrate (14) surface. The microwave radiation (18) is then interrupted to allow the coating (28) to cool, solidify, and mechanically bond to the substrate (14).

Abstract: A method of forming a metal coating on surfaces of internal passages of a turbine part (40) includes applying a nickel aluminum bond coating to an external surface of the turbine part, positioning the turbine part in a VPA chamber (88), coupling a gas manifold to at least one internal passage inlet, and coating at least a portion of the internal surface and the external of the turbine part by a vapor phase aluminiding (VPA) process using metal coating gases to form a coating on the internal surfaces of the turbine part.

Abstract: A process for forming a coating (28) on a surface of a substrate (14,24), in which the heating source for the coating process is microwave radiation (18) so that heating of the coating material is selective and sufficient to melt and bond the coating material to the substrate (14,24) without excessively heating the substrate (14,24). The process entails forming a coating material (10) containing powder particles (12) that are sufficiently small to be highly susceptible to microwave radiation (18).

Abstract: A method for applying an aluminide coating (76, 78) on a gas turbine engine blade (20, 132) having an external surface (40) and an internal cooling cavity (50) having an internal surface (52) that is connected to the external surface (40) by cooling holes (42). The method is conducted in a vapor coating container (110) having a hollow interior coating chamber (124), and includes the steps of loading the coating chamber (124) with the blade (20, 132) to be coated; providing an aluminide coating gas in the loaded coating chamber (124); flowing an inert carrier gas (150) into the loaded coating chamber (124) comprising the aluminide coating gas at a specified gas flow rate and time to move the aluminide coating gas through the cooling holes (42) and internal cooling cavity (50) and deposit an aluminide coating (76) on the internal surface (52) of the blade (20, 132); and then flowing an inert carrier gas (150) into the loaded coating chamber (124) comprising the aluminide coating gas at a specified higher temperature and time to deposit an aluminide coating (78) on the external surface (40) of the blade (20, 132).

Abstract: The present invention is process for forming diffusion aluminide coatings on an uncoated surface (36,38) of a substrate (42), without interdiffusing a sufficient amount of aluminum into a coating layer (44) to adversely affect the coating (44) growth potential and mechanical properties of said coating layer (44). A metal substrate (42) is provided comprising an external surface (36,38) and an internal passage (34) therein defined by an internal surface (36), at least a portion of the external surface (38) of the substrate (42) being coated with a coating layer (44) selected from the group consisting of beta -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 (42). The external surface (38) of the substrate (42) is cleaned. The metal substrate (42) 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 1.27 mols of fluorine per m /h (0.036 mols of fluorine per ft /h) of transport gas to about 6.36 mols of fluorine per m /h (0.18 mols of fluorine per ft /h) of transport gas, at a temperature in the range of about 1350 DEG F (730 DEG C) to about 1925 DEG F (1050 DEG 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 0.57 m /h to about 3.4 m /h (about 20 ft /h to about 120 ft /h) for a period of time in the range of about 2 hours to about 10 hours. The substrate (42) is then cooled. A superalloy article (20) coated with a diffusion aluminide layer (40) is obtained by using the diffusion aluminide coating process of the present invention.

A metal substrate (42) is provided comprising an external surface (36, 38) and an internal passage (34) therein defined by an internal surface (36), at least a portion of the external surface (38) of the substrate (42) being coated with a coating layer (44) selected from the group consisting of .beta.-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 (42). The external surface (38) of the substrate (42) is cleaned. The metal substrate (42) 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 (42) is then cooled. The present invention is also a superalloy article (20) coated with a diffusion aluminide layer (40) using the diffusion aluminide coating process of the present invention.
