Abstract
Systems and methods for forming an oxidation protection system on a composite structure are provided. In various embodiments, an oxidation protection system disposed on a substrate may comprise a boron-silicon-glass layer formed directly on the composite structure. The boron-silicon-glass layer may comprise a boron compound, a silicon compound, and a glass compound.
Claims8
An oxidation protection system disposed on an outer surface of a substrate, the oxidation protection system, comprising:
- a boron-silicon-glass layer disposed on the outer surface, the boron-silicon-glass layer comprising:
- a boron compound;
- a silicon compound;
- and
- a glass compound.
The oxidation protection system of claim 4, wherein the boron-silicon-glass layer is formed in direct contact with the outer surface of the substrate.
A method for forming an oxidation protection system on a composite structure, comprising:
- apply a boron slurry to the composite structure;
- performing a first low temperature bake by heating the composite structure at a first temperature;
- applying a silicon slurry to the composite structure;
- performing a second low temperature bake by heating the composite structure at a second temperature;
- and
- performing a high temperature heat treatment by heating the composite structure at a third temperature, the third temperature being greater than the first temperature and the second temperature.
