摘要：
"EQ coating", which was developed for a new thermal barrier coating system and was named from "Equilibrium Coating", is an oxidation-resistant coating using thermodynamically equilibrium state of the substrate and so it suppresses the interdiffusion between the substrate and coating layer. EQ coating and the ceramics top coat were applied to the 4th generation superalloy. EQ coating showed the excellent thermal barrier coating (TBC) life with the conventional yttria-stabilized zirconia (YSZ) system, and is able to be applied to the materials of the lower thermal conductivity. EQ coating was also applied to the 6th generation superalloy and its durability was evaluated. It is confirmed that the secondary reaction zone (SRZ) formation was suppressed and the interdiffusion at the interface was minimized, by cross section observation and concentration profile analysis.
