Abstract: A coating precursor slurry is provided, along with its methods of formation and use. The coating precursor slurry may include an organic binder comprising a polymeric component and a hardening reagent; an inorganic binder comprising an aluminum-nitrogen compound, a barium-containing organic compound, a nickel-containing organic compound, an ammonia polyphosphate, and phosphorus pentoxide; active components comprising Mo, Te, and graphite; and a solvent.

Abstract: A modified alloy is disclosed including a base alloy composition and an additive gamma prime antioxidant. The base alloy composition includes a concentration of a gamma prime antioxidant less than an effective concentration of the gamma prime antioxidant. The additive gamma prime antioxidant is intermixed with the base alloy composition to form the modified alloy, preferentially segregating to a gamma prime phase of the modified alloy and increasing the concentration of the gamma prime antioxidant to be at least the effective concentration of the gamma prime antioxidant. The effective concentration imparts reduced oxidation susceptibility of the gamma prime phase. An article is disclosed including the modified alloy. A coated article is disclosed including a coating disposed on a surface of an article having the base alloy composition. The coated article includes a reduced stress accelerated gamma prime oxidation static crack growth susceptibility in comparison with the base alloy composition.
