Abstract
Thermal barrier coatings for substrates comprising titanium. The thermal barrier coating may include a bond layer, an insulating layer, and a sealant layer. The bond layer may include titanium, a titanium alloy, an intermetallic compound of titanium, and/or a titanium metal matrix composite. The bond layer may have a superlattice structure having a periodically repeating group of layers. Methods for producing the thermal barrier coatings and articles of manufacture employing the thermal barrier coatings.
Claims15
A thermal barrier coating for a substrate, the thermal barrier coating comprising:
