PROBLEM TO BE SOLVED: To provide a heat resistant member provided with a thermal insulation coating layer having stable thermal conductivity even at a high temperature of ≥1,200°C and free from the cracks and peeling of the coating caused by sintering, and having excellent heat resistance and durability. SOLUTION: In the heat resistant member composed of: a base material 1 consisting of a metal or ceramic member; and a thermal isolation coating layer 4 applied to the surface of the base material 1, and in which the thermal insulation coating layer 4 is composed of a metal layer 2 functioning as a joining layer; and at least one ceramic layer 3 applied to the upper face of the metal layer 2, at least one layer of the ceramic layer(s) 3 is composed of a ceramic layer essentially consisting of hafnium oxide, and further, the ceramic layer comprises the hafnium oxide by ≥85%.

PROBLEM TO BE SOLVED: To provide a surface protection film capable of controlling the intrusion of corrosive gas better than before. SOLUTION: The surface protection film includes yttria (Y 2 O 3 ) as a principal component and cerium. By containing cerium, defects such as minute pores in the film are decreased and the intrusion of corrosive gas can be controlled. COPYRIGHT: (C)2011,JPO&INPIT

摘要:
PROBLEM TO BE SOLVED: To provide an article for use in a high-temperature environment and a method for protecting the article in such environment. SOLUTION: The article (10) includes: a substrate (20) consisting of silicon; a bonding coat (30)which consists of silicon and is arranged on the substrate (20); and an intermediate barrier (40)arranged on the bonding coat (30), and includes at least one layer (70). And at least one layer (70) includes: the intermediate barrier (40) which consists of rare earth silicate and does not substantially contain mullite; and a top coat (50) which consists of the rare earth-silicate and is arranged on the intermediate barrier (40).
