Patten, J W; Forcht, B A; Moss, R W

Composite protective coatings for protecting carbonaceous substrates from degrading in oxygen containing environments are provided. The composite protective coatings include a first coating layer applied to the surface of the substrate. The first coating layer is a silicon carbide type coating. The second coating layer is applied to the surface of a first coating layer and is a sputter deposited phase stabilized zirconium oxide having a columnar microstructure. Carbonaceous substrates having the composite protective coatings are able to withstand temperatures of about 4100/sup 0/ F. in oxygen containing environments.
