COMPOSITE MATERIAL PART WITH A SILICON-CONTAINING CERAMIC MATRIX PROTECTED AGAINST CORROSION |
摘要 |
The invention relates to an environmental barrier for a substrate made of a composite material with a ceramic matrix containing silicon, essentially SiC, which is formed by an anti-corrosion protection layer containing an aluminosilicate-type compound of an alkaline or alkaline-earth or rare-earth element, e.g. BSAS, with an aluminium nitride layer being interposed as a chemical barrier between the substrate and the anti-corrosion protection layer. |
