FORMING METHOD OF COATING LAYER FOR TURBOMACHINE COMPONENT, COMPONENT ITSELF, AND CORRESPONDING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a turbomachine component itself and a machine in which the component is installed, related to a forming method of a coating layer for the turbomachine component.

SOLUTION: A method for manufacturing a turbomachine impeller includes at least steps of: manufacturing the impeller 3 using a light alloy; and coating the impeller with a nickel-plating coating. The coating layer means a coating layer which incorporates an intermediate layer or to which a larger number of intermediate layers are added. Therefore, the coating is embedded with a larger number of layers which at least partially penetrate one another and are stacked in order.
