Abstract
An impeller for a rotary machine includes a base material of the impeller made of Al or an Al alloy. A surface layer for the impeller is formed by an electroless plating layer with a Ni—P based alloy and an under layer disposed between the base material and the surface layer, the under layer having a smaller Vickers hardness than the surface layer.
