Abstract
A composite that protects thermal barrier coatings from the deleterious effects of environmental contaminants at operational temperatures is discovered. The thermal barrier coated parts have least two outer protective coatings that decrease infiltration of molten contaminant eutectic mixtures into openings in the thermal barrier coating.
