  • HIGH TEMPERATURE THERMAL BARRIER COATING
    Publication number: 20140242411
    Abstract: A high temperature thermal barrier coating which consists of a stabilized ZrO2 composition for the protection of thermally loaded components (10, 10?) of a thermal machine, especially a gas turbine, is disclosed. The thermal barrier coating is stabilized with at least 15 mol % Y1+v Ta1?vO4?v, the ZrO2 is partially substituted by at least 10 mol % HfO2 and the composition is established according to the formula (Y1+vTa1?vO4?v)z(Zr1?xHfxO2)1?z, with x ranging from 0.1 to 0.5, v ranging from ?0.1 to 0.2 and z ranging from 0.15 to 0.25.
