COMPONENT FOR COMPRESSOR AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a component for a compressor capable of forming a minute oil sump by forming the surface of the component for the compressor into a mixing face having different hardness to improve oil holding property when operating the component for the compressor and eliminate troubles such as seizure and achieving reduction of input and long service life and having high reliability. SOLUTION: A raw material is molded by pressure fine particle sintering molding using iron alloy powders containing Cr, and nitriding treatment excluding carburized component is applied to form the surface having a mixing texture 3 composed of a compound layer 2 of Fe-Cr-N, a diffusion layer of Fe-Cr-N, and a base.
