THERMAL SPRAY POWDER FOR THERMAL BARRIER COATING, THERMAL BARRIER COATING, TURBINE MEMBER AND GAS TURBINE, AND METHOD OF PRODUCING THERMAL SPRAY POWDER FOR THERMAL BARRIER COATING
THERMAL SPRAY POWDER FOR THERMAL BARRIER COATING, THERMAL BARRIER COATING, TURBINE MEMBER AND GAS TURBINE, AND METHOD OF PRODUCING THERMAL SPRAY POWDER FOR THERMAL BARRIER COATING
PROBLEM TO BE SOLVED: To provide a material for a thermal barrier coating, having excellent high temperature crystal stability and high toughness, to provide a thermal barrier coating having a ceramic layer formed by using the material for the thermal barrier coating, and to provide a turbine member and a gas turbine having the thermal barrier coating.;SOLUTION: A thermal spray powder for the thermal barrier coating is represented by composition formula (1):SmxYbyZr(1-x-y)O((4-x-y)/2) (wherein 0x0.05, 0.06y0.11) or composition formula (2):SmxYyZr(1-x-y)O((4-x-y)/2) (wherein 0x0.05, 0.04y0.09). A method of producing the thermal spray powder for the thermal barrier coating has an electrically melting step and a granulating step using spray drying or the like after mixing raw materials.;COPYRIGHT: (C)2012,JPO&INPIT
