Abstract
Provided is high temperature equipment, such as gas turbine high temperature portion, usable in high temperature corrosion environment due to corrosive components and in erosion environment due to flying particles. Coating layer (2) in which Cr3C2 is finely dispersed in matrix MCrAlY, where weight ratio of MCrAlY/Cr3C2 is 1/1 to 3/1, is formed on base material (1) as sprayed coating and then diffusion heat treatment is added.
