Thermal resistant environmental barrier coating
A process for preparing a silicon based substrate with a protective coating having improved thermal resistance at temperature up to at least 1500°C, and the resulting article. The process comprising the steps of: providing a Si-containing substrate; and providing a protective coating on the substrate, the protective coating comprises at least a top coat which comprises at least an additive which inhibits the transmission of radiant energy in the wavelength region of the elecromagnetic spectrum of 0.7-5 microns.
