BONDCOAT FOR THE APPLICATION OF TBC'S AND WEAR COATINGS TO OXIDE CERAMIC MATRIX

A bond coat composition is provided for applying to the surface of a ceramic composite component between the composite substrate and the thermal barrier coat. The composition includes an alumina powder, a silica-yielding liquid, glass frits, and sufficient solvent to permit mixing of the components...
