    摘要： An intermetallic composition suitable for use as an environmentally-protective coating (24) on surfaces of components (10) used in hostile thermal environments, including the turbine, combustor and augmentor sections of a gas turbine engine. The coating (24) contains the gamma-prime (Ni 3 Al) nickel aluminide intermetallic phase and either the beta (NiAl) nickel aluminide intermetallic phase or the gamma solid solution phase. The coating (24) has an average aluminum content of 14 to 30 atomic percent and an average platinum-group metal content of at least 1 to less than 10 atomic percent, the balance of the coating (24) being nickel, incidental impurities, and optionally hafnium.

    摘要： An overlay coating (24) for articles used in hostile thermal environments. The coating (24) has a predominantly gamma prime-phase nickel aluminide (Ni 3 Al) composition suitable for use as an environmental coating and as a bond coat for a thermal barrier coating. The coating (24) has a composition of, by weight, at least 6% to about 15% aluminum, about 2% to about 5% chromium, optionally one or more reactive elements in individual or combined amounts of up to 4%, optionally up to 2% silicon, optionally up to 60% of at least one platinum group metal, and the balance essentially nickel. A thermal-insulating ceramic layer (26) may be deposited on the coating (24).

    摘要： A process for reducing the incidence of a secondary reaction zone (SRZ) in alloys prone to SRZ formation, particularly superalloys that have a high refractory element content is described. The process finds use with articles having a wall region (22) that defines external and internal surfaces on the exterior and within the article, respectively. Diffusion coatings (32) are formed on the internal and external surfaces of the article, with at least the diffusion coating (32) on the external surface comprising an additive layer (34) and a diffusion zone (36) that is beneath the additive layer (34) and extends into the wall region (22). The additive layer (34) and at least a portion of the diffusion zone (36) of the external diffusion coating (32) is then removed to define an exposed surface region on the exterior of the article. An overlay coating (24) is then deposited on the exposed surface region.
