ABSTRACT:
A thermal barrier coating material can prevent spall-off from occurring during operation at high temperatures and has a high heat insulating effect. A turbine parts and a gas turbine that are protected with the thermal barrier coating material are also provided. The thermal barrier coating material of the present invention comprises a ceramic layer23, which is formed on a high temperature heat-resistant alloy base21to protect the base21from high temperatures, the ceramic layer23being applied via a bonding coat layer22provided as a metal bonding layer and is made of ZrO2with Er2O3added thereto as a stabilizing agent. The turbine parts and the gas turbine of the present invention are coated with the thermal barrier coating material on the surfaces thereof.
