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° 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 Al2 O3, ZrO2 and Y2 O3, the transition metal oxides MnO, CoO, NiO and FeO, and MgO.
