摘要：
A composite is described which has particular utility in the formation of components for gas turbine engines. The composite broadly comprises a substrate having a surface and at least one layer of a BN/Si3N4 coating on the substrate surface. The coating preferably is formed by alternative layers of a BN material and a Si3N4 material. The substrate may be a cloth material with fibers, such as SiC fibers, woven therein.
