METHOD FOR PRODUCING A HEAT-SHIELDING COATING, TURBINE MEMBER PROVIDED WITH SAID HEAT-SHIELDING COATING, AND GAS TURBINE

摘要

A process for producing a thermal barrier coating having an excellent thermal barrier effect and superior durability to thermal cycling. Also, a turbine member having a thermal barrier coating that has been formed using the production process, and a gas turbine. The process for producing a thermal barrier coating includes: forming a metal bonding layer (12) on a heat-resistant alloy substrate (11), and forming a ceramic layer (13) on the metal bonding layer (12) by thermal spraying of thermal spray particles having a particle size distribution in which the 10% cumulative particle size is not less than 30 µm and not more than 100 µm.
