Abstract:
A thermal and environmental barrier coating composed of ceramic hollow microspheres sintered together. In one embodiment the microspheres are sintered together with a powder of another material that acts as a binder, or with a powder of a material that may be the same as the material of the hollow microspheres, forming a matrix in which the hollow microspheres are embedded. The hollow microspheres may be composed of a material with a high temperature capability, and with a low coefficient of thermal expansion.
