摘要

A superalloy turbine blade (10) has a bond coating (92) and a thermal barrier coating (94). The bond coating (92) comprises a MCrAlY coating on the metallic substrate (90) of the superalloy turbine blade (10), an aluminide coating on the MCrAlY coating and an alumina interface layer (94) on the aluminide coating. The thermal barrier coating (96) is on the alumina interface layer (94). The aluminide coating on the MCrAlY provides more aluminium to bond the thermal barrier coating (6) onto the metallic substrate (90). <IMAGE>
