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.
