    摘要： The invention is a class of nickel-base alloys for gas turbine applications, comprising, by weight, about 13.7 to about 14.3 percent chromium, about 5.0 to about 10.0 percent cobalt, about 3.5 to about 5.2 percent tungsten, about 2.8 to about 5.2 percent titanium, about 2.8 to about 4.6 percent aluminum, about 0.0 to about 3.5 percent tantalum, about 1.0 to about 1.7 percent molybdenum, about 0.08 to about 0.13 percent carbon, about 0.005 to about 0.02 percent boron, about 0.0 to about 1.5 percent niobium, about 0.0 to about 2.5 percent hafnium, about 0.0 to about 0.04 percent zirconium, and the balance substantially nickel. The nickel-base alloys may be provided in the form of useful articles of manufacture, and which possess a unique combination of mechanical properties, microstructural stability, resistance to localized pitting and hot corrosion in high temperature corrosive environments, and high yields during the initial forming process as well as post-forming manufacturing and repair processes.

    摘要： A thermal barrier coating (TBC) system is provided. The system includes at least one thermal barrier coating (TBC) bond coat layer formed over a substrate surface region. The TBC bond coat layer includes at least one TBC bond coat material. The TBC bond coat material is a nickel-chromium-aluminum-yttrium (NiCrAlY) composition that also includes silicon (Si), hafnium (Hf) and less than 10 weight percent (wt %) cobalt (Co). The TBC system further includes at least one top coat layer formed over the TBC bond coat layer.
