Thermal barrier system and bonding method

摘要

A composite article (30) includes a substrate (46), a ceramic member (50) on the substrate (46) and a ceramic bond coat (52) for securing the substrate (46) and the ceramic member (50) together. A method of securing the ceramic member (50) and the substrate (46) together includes pyrolyzing a ceramic precursor, such as a ceramic powder, between the substrate (46) and the ceramic member (50) to form the ceramic bond coat (52).
