  • Thermal barrier coating system
    Patent number: 4055705
    Abstract: A coating system which contains a bond coating and a thermal barrier coating is applied to metal surfaces such as turbine blades and which provides both low thermal conductivity and improved adherence when exposed to high temperature gases or liquids. The bond coating contains NiCrAlY and the thermal barrier coating contains a reflective oxide. The reflective oxides ZrO.sub.2 --Y.sub.2 O.sub.3 and ZrO.sub.2 --MgO have demonstrated significant utility in high temperature turbine applications.
