Abstract
An oxidation-sensitive composite has applied thereto a composition comprising a mixture of boride powder constituted for the most part of TiB2, at least one vitreous refractory oxide powder constituted for the most part by a mixture of borosilicate glass, and a binder containing a ceramic-precursor resin. The resin is cured and is subsequently transformed into a ceramic by heat treatment or during first exposure of the coated part to high temperatures.
