Al 합금 기재 (41) 와, Al 합금 기재 (41) 의 표면에 형성된 무전해 도금층 (42) 과, 무전해 도금층 (42) 의 표면에 형성된 Si 층 (43) 또는 내식성 금속층 (53) 과, Si 층 (43) 또는 내식성 금속층 (53) 의 표면에 형성된 다이아몬드 라이크 카본층 (44) 또는 세라믹층 (54) 을 구비하는 내환경성 부재에 의해, 압축기의 날개차를 형성함으로써, 그 날개차에 내이로전성 및 내코로전성을 겸비시킬 수 있다. This environment-resistant member is provided with: an Al alloy base material (41); an electroless plating layer (42) formed on the surface of the Al alloy base material (41); a Si layer (43) or a corrosion-resistant metal layer (53) which is formed on the surface of the electroless plating layer (42); and a diamond-like carbon layer (44) or a ceramic layer (54) which is formed on the surface of the Si layer (43) or on the surface of the corrosion-resistant metal layer (53). By forming an impeller of a compressor using said environment-resistant member, the impeller can achieve both erosion resistance and corrosion resistance.
