Abstract: There is disclosed a coated article composed of a metal alloy substrate, the metal alloy having a nickel, chromium, cobalt or iron base, and a coating that serves as an oxygen barrier to insulate the metal surface from oxygen attack at temperatures which may range up to 1200 DEG C. The coating comprises a glass-ceramic selected from barium silicate and strontium silicate systems characterized by additives that enable forming a continuous well flowed glass coating prior to setting of the coating by crystallization. These additives include the refractory oxides Al2O3, ZrO2 and Y2O3, the transition metal oxides MnO, CoO, NiO and FeO, and MgO.

Abstract: A coated article, for use at above 1000 deg.C in an oxygen-contg. environment, consists of a Ni, Co, Cr or Fe based alloy substrate and an oxygen barrier coating. The coating consists of either (a) a glass-ceramic comprising (by wt.) barium silicate (20-65% BaO and 25-65% SiO2) max. 50% additive and max. 5% B2O3 + R2O (R = Na, K, Li) or strontium silicate (20-60% SrO and 30-70% SiO2), max. 40% additive and max. 5% B2O3 + R2O, the additive comprising one or more of up to 15% Al2O3, up to 15% ZrO2, up to 15% Y2O3, up to 25% MnO, up to 25% NiO, up to 30% MgO, up to 30% CoO and up to 40% iron oxide; or (b) a glass-ceramic having a main crystalline phase selected from barium silicate-type, strontium silicate-type and cristobalite phase and contg. cristobalite crystals conc. near the interface between the glass-ceramic and the metal substrate.
