ABSTRACT:
Coatings which protect the skin of hypersonic flight vehicles are disclosed. Silicide coatings, such as R512E, is used to minimize catalytic recombination of dissociated species, such as atomic oxygen and atomic nitrogen, thus, decreasing thermal and oxidative degradation. Prehydrated, polymerized sol of tetraethylorthosilicate is applied to a coating, and is fired, to produce an integral protective coating.
