Abstract:
A system of layers in a protective coating (20) for a substrate (22), including at least an outer thermal barrier layer (32) and a tungsten bronze structure ceramic underlayer (30) that reduces spalling of the outer layer. The range of materials for the underlayer includes ceramics of the form Ba6−3mRe8+2mTi18O54, where 0
