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. Also, disclosed is a method for maintaining the silicon content of protective coatings for the skin of hypersonic flight vehicles, including the steps of applying a prehydrated, polymerized sol of tetraethylorthosilicate to a coating, and firing, to produce an integral protective coating.
