Abstract
A solid particle erosion resistant surface treated coating has a solid particle erosion resistance that is largely enhanced and a rotating member having the coating gains oxidation resistance without deteriorating a fatigue strength. Also, a rotating machine can have this coating applied thereto. The solid particle erosion resistant surface treated coating has a nitrided hard layer formed on a surface of a base material and a PVD (physical vapor deposition) hard layer of at least one layer formed on the nitrided hard layer by a PVD method. Deformation of the base material by collisions by solid particles is prevented and cracking of the coating is prevented. Thereby, the solid particle erosion resistance is secured, life of the solid particle erosion resistant surface treated coating can be increased and oxidation resistance and fatigue strength are enhanced.
