摘要： A method for coating a substrate includes spraying a combination of powders. The combination of powders includes: Hf0.5Si0.5O2; Zr0.5Si0.5O2; and, optionally, at least one of HfO2 and ZrO2. A molar ratio of said Hf0.5Si0.5O2 and HfO2 combined to said Zr0.5Si0.5O2 and ZrO2 combined is from 2:1 to 4:1. A molar ratio of said Hf0.5Si0.5O2 to said HfO2 is at least 1:3.

摘要： An environmental barrier coating includes a barrier layer which includes a matrix, diffusive particles, and gettering particles; and a calcium-magnesia alumina-silicate (CMAS)-resistant component. The CMAS-resistant component includes hafnium silicate and a rare earth hafnate. An article and a method of fabricating an article are also disclosed.
