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: A refrigerant compressor reserves lubricating oil with a viscosity of VG2 to VG100 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. The compression component includes at least one slide member comprising a base material 171 made of an iron-based material and an oxide coating film 170 provided on a surface of the base material 171. The oxide coating film 170 includes: a portion containing diiron trioxide (Fe2O3), in a region which is closer to an outermost surface of the oxide coating film; and a silicon containing portion containing silicon (Si) which is more in quantity than silicon (Si) of the base material 171, in a region which is closer to the base material 171.
