摘要：
A method for protecting thermal barrier coatings deposited on engine parts from the deleterious effects of environmental contaminants at high temperatures is given. The method uses a sacrificially consumed oxide coating with the thermal barrier coating, where the consumption of the oxide coating increases the melting temperature of a contaminant composition above the surface temperature of the thermal barrier coating, or increases the viscosity of the contaminant composition to prevent its infiltration into the thermal barrier coating.
