METHOD FORR TREATING METAL SURFACE ROTARY SHAFT FOR REFRIGERANT COMPRESSOR TREATED BY THE METHOD VANE FOR REFRIGERANT COMPRESSOR TREATED BY THE METHOD AND REFRIGERANT COMPRESSOR USING THE SAME

摘要

A refrigerant compressor comprising a compression element driven by a rotating shaft and configured to compress and discharge a sucked HFC refrigerant or a refrigerant mainly composed of HFC refrigerant by this compression element, and to perform plasma sulfur nitriding treatment on the surface of the rotary shaft. The implemented rotation shaft is used. Alternatively, a vane subjected to plasma sulfidation treatment is used on the surface of the vane made of high speed tool steel equivalent steel. Thus, even when an ester refrigerant oil or an ether refrigerant oil is used as the refrigerant oil and an HFC refrigerant is used, the friction coefficient at the sliding portion of the rotating shaft or the surface of the vane is low, and a rotating shaft or vane having high wear resistance is provided. It is possible to provide a refrigerant compressor.
