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.degree. F. in oxygen containing environments.

Composite protective coating for carbon-carbon substrates

A material and process for preparing corrosion resistant reflective material. The process in the preferred embodiment comprises abrading a metal substrate, anodizing the metal substrate, depositing a thin film of substantially pure metal on the anodized substrate, and covering the reflective metal with a protective organic coating. The material produced is a metallic substrate having an anodized layer with a relatively thin film of reflective metal covered by a protective organic coating.
