Abstract
A method for forming an oxidation protection system on a composite structure are provided. The method includes applying a composite slurry to the composite structure, wherein the composite slurry comprises boron carbide, silicon carbide, borosilicate glass, an oxygen reactant compound including a silica forming component, and a carrier fluid and heating the composite structure to a temperature sufficient to form a boron-silicon-glass-oxygen reactant layer on the composite structure.
