Abstract
A thermal barrier coating enabling to prevent peeling of layer in a high temperature use and still having a high thermal barrier effect, a turbine part coated by this thermal barrier coating and a gas turbine comprising this turbine part are provided. The thermal barrier coating comprises a base materialof high temperature heat resistant alloy and a ceramics layerformed on the base material. The ceramics layercomprises ZrOadded with YbOas stabilizer and is laminated on the base material via a bond coat layerlaminated as a metallic bond layer. A plurality of cracksA are preferably introduced in the ceramics layer. The turbine part is constructed having its surface coated with the above thermal barrier coating.
