摘要： A coating process and coated article are disclosed. The coating process includes positioning an article relative to an inductor, heating the article with the inductor, then applying a coating material over the article to form a crystalline coating. The heating of the article increases a first temperature of a surface of the article to a second temperature favoring crystal formation. Another coating process includes positioning an article, uniformly heating a surface of the article to a second temperature favoring crystal formation, then applying an environmental barrier coating material over the surface of the article to form a crystalline environmental barrier coating. The application of the environmental barrier coating is performed through air plasma spray deposition. The coated article includes an article having a complex geometry, and a crystalline coating applied on a surface of the article. The crystalline coating includes increased resistant to delamination.

摘要： A method of forming an article includes forming a silicon-containing layer on a silicon-containing region of a surface of a substrate of the article; forming a plurality of channels and ridges in the silicon-containing layer; and forming at least one outer layer overlying the surface of the silicon-containing region. The plurality of channels and ridges may be formed by adding silicon-containing material to the silicon-containing layer. The channels and ridges may be formed by subtracting material from the silicon-containing layer. The channels and ridges may be formed by forming channels or grooves in the silicon-containing region of the surface of the substrate prior to formation of the silicon-containing layer.
