ENVIRONMENTAL BARRIER COATED CERAMIC MATRIX COMPOSITE COMPONENT AND METHOD FOR MANUFACTURING SAME

摘要

A ceramic matrix composite component (10) coated with environmental barrier coatings includes a substrate (12) formed of a silicide-containing ceramic matrix composite, a silicon carbide layer (14) deposited on a surface of the substrate (12), a silicon layer (16) deposited on a surface of the silicon carbide layer (14), a mixed layer (18) made of a mixture of mullite and ytterbium silicate and deposited on a surface of the silicon layer (16), and an oxide layer (20) deposited on a surface of the mixed layer (18).
