    Abstract: Method for localized aluminide coating applied for the first time or as repair includes creating a contained space by disposing coating material comprising an aluminum source and a halide activator at least partially over and in an out-of-contact relation with a target surface of a metal substrate. Heating the substrate to a temperature to cause the aluminum source to react with the halide activator and the substrate results in diffusion aluminide coating of the targeted surface. An article comprising a target surface of a metal substrate, said surface bounding a contained space, and a coating tape comprising an aluminum source and a halide activator and disposed in an out-of-contact relation at least partially over the contained space whereby, when the substrate is heated to a temperature to cause the halide activator to react with the aluminum source, a diffusion aluminide coating is formed on the target surface.

    Abstract: In a thermal spray apparatus (1) a plasma stream passes through a nozzle (2) towards a substrate (20). On entering the nozzle (2), the plasma stream passes through a plasma cooling passageway (10), to a plasma accelerating zone (11) defined by a narrowed passageway, and then into an expanded plasma/particle confining zone (12, 18) for the discharge of material from the nozzle (2). To apply thermal spray coatings (21) of increased hardness to a substrate (20), the ratio of length of the plasma/particle confining zone (12, 18) relative to the diameter of the plasma/particle confining zone (12, 18) is increased from the more conventional value to about 5:1, preferably to a ratio in the range of from 7:1 to 16.5:1. Ratios of from 10:1 to 13:1 have been found to achieve a particularly desirable result. Also the method and the coatings obtained.

    Abstract: Known thermal spray apparatus are modified to achieve rough thermal spray coatings. Thermal spray apparatus operate to develop a plasma stream for introduction to a nozzle, for eventual application to the surface of a substrate. Upon entering the nozzle, the plasma stream is passed through a plasma cooling zone defined by a plasma cooling passageway, to a plasma accelerating zone defined by a narrowed passageway that expands into a plasma/particle confining zone for the discharge of material from the apparatus. The narrowed passageway of the apparatus is cooled, and the powder material to be applied by the apparatus is introduced into the plasma stream along the cooled, narrowed passageway. For the appropriate heating (melting) and acceleration of MCrAlY powder particles, for application to the substrate which is to receive the thermal spray coating, the ratio of the initial (plasma cooling) passageway relative to the narrowed (plasma accelerating) passageway is reduced from the more conventional value of about 4:1 to a ratio of 2:1 or less.

    Abstract: A silicon-enriched aluminide coating for a superalloy article has a composite microstructure including a plurality of bands of silicon rich phases (S1, S2, S3) and a plurality of bands of aluminum rich phases (A1, A2, A3), these bands being spaced apart through the thickness of the coating. The composite microstructure is created by depositing a slurry containing both silicon and aluminum in elemental or pre-alloyed form on the article and heating the coated article above the melting temperature of aluminum to cure the coating, the depositing and curing steps being repeated at least once before diffusion heat treating the resulting layers. Thereupon, all the above process steps are repeated at least once.
