摘要： A refrigerant compressor for using HFC 134a as a refrigerant and a refrigerator oil such as polyether type oil, polyester type oil, or the like which is compatible thereto is disclosed. The refrigerant compressor has a iron type substrate with a compound layer mainly made of iron sulfide on sliding portions such as sliding parts and shaft in the compression mechanism. The sliding parts in the compression mechanism are a cylinder and a rotor and a piston which are moving parts. In a rotary type compressor, the sliding parts are a blade and so forth. The hardness of the compound layer mainly made of the aforementioned iron sulfide is large and thereby effectively preventing metals from being contacted and preventing adhesive abrasion which is the primary cause of the abrasion of the sliding portions. In addition, since the compound is stable in a moist situation, even if it is used along with polyether type oil, polyester type oil, or the like and HFC 134a, corrosion and abrasion due to dissolving of compound layer can be prevented.

摘要： A compressing mechanism includes a slidable section which is constructed by combining a first slidable member made of a cast iron having a Vickers hardness within the range of 200 to 300 with a second slidable member made of a carbon steel having a Vickers hardness within the range of 200 to 300 and an average number of crystalline grains per 1 mm.sup.2 within the range of 2000 to 3200. The slidable section is composed of a shaft and a bearing. Additionally, the slidable section includes a cylinder, a rotor and a piston. Each crystalline grain in the carbon steel constituting the second slidable member has a substantially isotropic shape and a size of the crystalline grain is suitably enlarged to exhibit a coarse structure. As a result, elasticity of the grain structure of the carbon steel is increased and a very small number of crystalline grains are peeled off from the surface of the substrate. Since the slidable section is constructed by combining the first slidable member with the second slidable member in the above-described manner, the second slidable member exhibits excellent wear resistance even under a circumstance wherein the 1,1,1,2-tetrafluoroethane or the 1,1-difluoroethane is used as a refrigerant in the presence of a polyether-based oil, a polyester-based oil or the like each serving as a refrigerator oil.
