METHOD OF MANUFACTURING SLIDING PART AND COMPRESSOR PROVIDED WITH THE SLIDING PART INEXPENSIVE AND WEAR-RESISTANT

摘要

PURPOSE: To provide a method of manufacturing a sliding part which is inexpensive and wear-resistant and a compressor provided with the sliding part. CONSTITUTION: The method of manufacturing a sliding part(10) comprises the steps of forming a green member by injection molding integrally and unmixedly a first iron series powdery metallic alloy containing less than 6% of chromium and a second iron series powdery metallic alloy containing not less than 6% of chromium; sintering the green member; and subjecting the green member to at least one heat treatment. In a compressor, the improvement comprises a sliding part which is obtained by injecting molding integrally and unmixedly two powdery metallic materials of different compositions into a green member, sintering the green member and subjecting the green member to at least one heat treatment; and a shaft which is engageable with the sliding part and is made of a material different from those of the sliding part so as to have a hardness different from those of the sliding part.
