Abstract: A sealed refrigerant compressor (100) includes: a compression element (107) accommodated in a sealed container (101) and configured to compress a refrigerant; and an electric element (106) configured to drive the compression element (107). Lubricating oil (103) is stored in the sealed container (101). A resin member is included as a member accommodated in the sealed container (101). The amount of oligomer contained in the resin member is 2.5 wt. % or less of an entire weight of the resin member. Kinetic viscosity of the lubricating oil 103 at 40° C. falls within a range of 0.1 to 5.1 mm2/s. A flash point of the lubricating oil 103 is 110° C. or more.

Abstract: 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).

Abstract: 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.
