Abstract
A method is provided for protecting thermal barrier coatings deposited on parts from the deleterious effects of environmental contaminants at operating temperatures. The method uses an impermeable barrier coating with the thermal barrier coating, where the impermeable barrier coating prevents environmental contaminants and resulting contaminant compositions from infiltrating openings in thermal barrier coatings during service at operating temperatures.
