  • Method of depositing a coating on Si-based ceramic composites
    Patent number: 6787195
    Abstract: A process of depositing a coating system suitable for use as an environmental barrier coating on various substrate materials, particularly those containing silicon and intended for high temperature applications such as the hostile thermal environment of a gas turbine engine. The process comprises depositing a first coating layer containing mullite, and preferably a second coating layer of an alkaline earth aluminosilicate, such as barium-strontium-aluminosilicate (BSAS), by thermal spraying while maintaining the substrate at a temperature of 800° C. or less, preferably 500° C. or less, by which a substantially crack-free coating system is produced with desirable mechanical integrity.
    Type: Grant
