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, one or more of chromium, silicon, tantalum, and cobalt, optionally one or more of hafnium, yttrium, zirconium, lanthanum, and cerium, and incidental impurities.

摘要： A protected article has a substrate (30) and a protective structure (33) overlying a surface (32) of the substrate (30). The protective structure (33) includes a protective layer (34) overlying the surface (32) of the substrate (30) and having an aluminum content greater than that of the substrate (30), and a bond-coat layer (40) of a bond-coat-layer metal. The bond-coat-layer metal has a bond-coat initial composition having at least about 60 percent by weight platinum, rhodium, palladium, or combinations thereof. There may be a diffusion-barrier layer between the surface (32) of the substrate (30) and the protective layer (34), and there may be a ceramic thermal barrier coating overlying the bond-coat layer (40).
摘要翻译：受保护制品具有覆盖在衬底（30）的表面（32）上的衬底（30）和保护结构（33）。保护结构（33）包括覆盖在基板（30）的表面（32）上并具有大于基板（30）的铝含量的铝含量的保护层（34），以及粘合涂层粘结层层金属。键合层层金属具有至少约60重量％的铂，铑，钯或其组合的键层初始组成。在基板（30）的表面（32）和保护层（34）之间可能存在扩散阻挡层，并且可以存在覆盖在粘合涂层（40）上的陶瓷热障涂层。
