THERMAL BARRIER COATING FORMATION METHOD, THERMAL BARRIER COATING, AND HIGH-TEMPERATURE MEMBER

摘要

A thermal barrier coating is provided that includes a ceramic layer (120) formed on a heat-resistant alloy substrate and containing a ceramic. The ceramic layer (120) has: a first dense layer (121); an intermediate porous layer (122) which is laminated on the first dense layer (121), which has a higher density than the first dense layer (121), and in which numerous pores are formed; and a second dense layer (123) that is laminated on the intermediate porous layer (122) and has a lower density than the intermediate porous layer (122).
