ABSTRACT:
A coating system (20) for articles used in hostile thermal environments, such as turbine, combustor and augmentor components (10) of a gas turbine engine. The coating system (20) of this invention employs a NiAl-based intermetallic coating (24) containing 30 to 60 atomic percent aluminum so as to be predominantly of the .beta.-NiAl phase, but also contains alloying additions intended to increase the creep strength of the coating (24), and optionally contains alloying additions to getter impurities, increase fracture resistance, and promote oxidation resistance. For this purpose, the coating (24) preferably includes additions of chromium, titanium, tantalum, silicon, hafnium and/or gallium, and optionally contains additions of calcium, zirconium, yttrium, and/or iron.
