Abstract
A high temperature resistant structure which is capable of withstanding temperatures well in excess of 2500 degrees Fahrenheit in oxidizing environments for periods of at least several hours. A high temperature resistant substrate such as carbon carbon composite is coated in situ with very thin alternate layers of silicon carbide and a carbide formed from hafnium or zirconium. The coating is preferably formed using chemical vapor deposition procedures.
