    摘要: PROBLEM TO BE SOLVED: To provide a high temperature member for a gas turbine having a thermal barrier coating in which heat resistance property is improved.SOLUTION: In a high temperature for a gas turbine having a thermal barrier coating and a cooling structure, fine passages communicating from a base material side to a front face side are provided in the alloy substrate layer of the thermal barrier coating and in a thermal barrier ceramic layer, and a part of refrigerant cooling the member is flowed out to the outside of the member through the fine passages. Consequently, a heat resistant temperature improvement effect of the high temperature member, due to a leaching-out cooling effect, can be expected.
