Abstract

A method of preparing a ceramic matrix composite (CMC) article is disclosed. The method includes depositing a first layer of a coating composition directly onto a surface of a silicon carbide fiber-reinforced silicon carbide matrix (SiC/SiC) composite substrate, with the coating composition comprising a rare earth silicate and a sintering aid. The method also includes heating the first layer to sinter the coating composition to form an environmental barrier coating (EBC) adjacent the SiC/SiC composite and a transition layer integrally bonded to and between the substrate and the EBC. CMC articles prepared according to the method, including coated turbomachine components, are also disclosed.
