Abstract
A method for coating a composite structure, comprising applying a first slurry onto a surface of the composite structure, wherein the first slurry is a sol gel comprising a metal organic salt, a first carrier fluid, and a ceramic material, and heating the composite structure to a first sol gel temperature sufficient to form a sol gel-derived base layer on the composite structure.
Claims2
A sol gel for coating a composite structure with an oxidation protection system, comprising:
- a carrier fluid;
- a metal organic salt comprising aluminum tri-sec butoxide;
- ethanol;
- acetic acid;
- methanol;
- and
- a ceramic material comprising at least one of a carbide, a boride, or a nitride,
- wherein the sol gel is configured to mitigate oxidation of the composite structure.
