Abstract

Provided are a thermal barrier coating material and a member coated with thermal barrier that can suppress the separation when used at a high temperature, and have a high thermal barrier effect; a method for manufacturing the member coated with thermal barrier; a turbine member coated with the thermal barrier coating material; and a gas turbine. More specifically provided are a shield coating member comprising a heat-resistant substrate, a bond coat layer formed on the heat-resistant substrate, and a ceramic layer formed on the bond coat layer, wherein the ceramic layer comprises a ceramic represented by a general formula A 2 Zr 2 O 7 , wherein A denotes a rare earth element, and the ceramic layer has (a) a porosity of 1 to 30%, (b) cracks in a thickness direction in pitches of 5 to 100% the total thickness of layers other than the bond coat layer on the heat-resistant substrate, or (c) columnar crystals.
