摘要： A refrigerant compressor reserves lubricating oil in a sealed container, and accommodates therein an electric component, and a compression component which is driven by the electric component and compresses a refrigerant. At least one of slide members included in the compression component is made of an iron-based material, and an oxide coating film comprising a composition A portion, a composition B portion, and a composition C portion is provided on a slide surface of the iron-based material. The composition A portion is a portion containing diiron trioxide (Fe2O3) which is more in quantity than other substances, and is, for example, an outermost portion (160a). The composition B portion is a portion containing triiron tetraoxide (Fe3O4) which is more in quantity than other substances and containing a silicon (Si) compound, and is, for example, an intermediate portion (160b). The composition C portion is a portion containing triiron tetraoxide (Fe3O4) which is more in quantity than other substances and containing silicon (Si) which is more in quantity than silicon (Si) of the composition B portion, and is, for example, an inner portion (160c).

摘要： The present invention includes: an electric component; a compression component driven by the electric component to compress a refrigerant; and a sealed container accommodating the electric component and the compression component. The compression component includes: a shaft part rotated by the electric component; and a bearing part slidingly contacting the shaft part such that the shaft part is rotatable. A film having hardness equal to or more than hardness of a sliding surface of the bearing part is provided on a sliding surface of the shaft part. The sliding surface of the bearing part includes a curved-surface portion having an inner diameter that continuously increases in a curved shape toward an end of the bearing part in a center axis direction of the bearing part, or the sliding surface of the shaft part includes a curved-surface portion having an outer diameter that continuously decreases in a curved shape toward an end of the shaft part in a center axis direction of the shaft part.

摘要： An oxide film (170) is formed on a surface of a base material (175) that is a sintered body constituted by an iron-based material. The oxide film (170) includes a first layer (171), a second layer (172), and a third layer (173). The first layer (171) is located on an outermost surface and is constituted by at least fine crystals. The second layer (172) is located under the first layer (171) and contains columnar structures. The third layer (173) contains columnar structures and is provided on the second layer (172) through an interface (174) so as to be located close to the base material (175). The first layer (171) includes a dense layer (171a). The oxide film (170) can exhibit satisfactory abrasion resistance.

摘要： A refrigerant compressor includes: an electric component (106); a compression component (107) driven by the electric component to compress a refrigerant; and a sealed container (101) accommodating the electric component and the compression component. The compression component includes: a shaft part (109, 110) rotated by the electric component; and a bearing part (114, 119) slidingly contacting the shaft part such that the shaft part is rotatable. A film (160) having hardness equal to or more than hardness of a sliding surface of the bearing part is provided on a sliding surface of the shaft part. Surface roughness of the sliding surface of the bearing part is smaller than surface roughness of the sliding surface of the shaft part.

摘要： A refrigerant compressor includes: an electric component; and a compression component driven by the electric component to compress a refrigerant. At least one sliding member constituting the compression component is made of a base material (185) that is an iron-based material. An abrasion resistance film (180) including a surface layer constituted by at least fine crystals is formed on a sliding surface of the sliding member. The surface layer (181) includes an A portion in which a component contained most is diiron trioxide (Fe2O3). The A portion exists within a range of at least 0.3 μm or less from an outermost surface of the sliding surface. The abrasion resistance film (180) may include at least one intermediate layer (182 to 184) located between the surface layer (181) and the base material (185). With this, self-abrasion resistance of the sliding member can be improved, so that the refrigerant compressor having excellent reliability and efficiency can be obtained.
