1. A coated article, comprising:
an article having a surface;
an oxidation resistant bond coat layer deposited on the surface, the oxidation resistant bond coat layer comprising a healing silica matrix and at least one oxygen scavenger as a metallic, intermetallic, or metal silicide network dispersed within the healing silica matrix, wherein interstices in the metallic, intermetallic, or metal silicide network are at least partially filled with the silica healing matrix; and
an environmental protective top coat layer disposed upon the oxidation resistant bond coat layer, wherein, upon formation of a crack in the environmental protective top coat layer, the oxidation resistant bond coat layer is operable to repair the crack.
