Abstract
A composite that protects thermal barrier coatings on parts from the deleterious effects of environmental contaminants at operating temperatures with an impermeable barrier coating is divulged. The thermal barrier coating composite decreases infiltration of molten contaminant compositions into openings in the thermal barrier coating to increase the life of the composite.
