Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat resistant member provided with a thermal barrier coating which has excellent durability and usable, e.g. for a gas turbine and an aircraft engine having extremely high driving temperature. SOLUTION: In the heat resistant member, a thermal barrier layer 3 composed of ceramics via a bonding layer 2 of an alloy substantially consisting of at least one selected from Ni and Co, Cr and Al is provided on the surface of a heat resistant alloy base material 1 essentially consisting of at least one selected from Ni and Co. The alloy in the bonding layer can comprise at least one selected from the group consisting Ta, W, Si, Pt, Mn and B in the range of 0 to 20 wt.%. In the heat resistant member, the durability of the thermal barrier ceramic layer is extremely excellent, and its peeling damage is hard to occur. COPYRIGHT: (C)2010,JPO&INPIT
