    Abstract: The invention provides a refrigerant compressor that is capable of preventing seizure or galling at the bearing slide section and has high anti-wear properties.The refrigerant compressor includes a compressor mechanism for compressing a refrigerant. The compressor mechanism includes a fixed scroll 100 and an orbiting scroll 200, and the two scrolls are mutually meshed. The refrigerant compressor also includes a rotary shaft 300 for driving the compressor mechanism. A plain bearing(s) is/are provided either at the joint section between the rotary shaft and the compressor mechanism or at the support section supporting the rotary shaft or at both of the two sections. The plain bearing(s) is/are formed of lead-free resin-impregnated material capable of adsorbing wear particles, and the rotary shaft is formed of iron material. The section of the rotary shaft that slides against the plain bearing(s) is covered with a hard film 1000 of a hardness of 1000 Hv or more.

    Abstract: The invention relates to a method for applying electro-deposited metal coatings (3) upon aluminium or aluminium alloy components (1). According to said method, the surface (4) of the component is cleaned in an appropriate solution, in particular a solution of oils, fats, emulsions, pigments, etc. Said surface (4 ) is then etched in an appropriate solution, such that a certain quantity of material or near-surface alloy constituents is dissolved. After cleaning and dissolution, water rinsing is carried out. Immediately after the dissolution of the near-surface regions, the surface (4) of said component (1) is activated in a solution, containing iron ions, with a sulphate base by the anodic coupling of said component (1). The functional layer (3) is then applied by the cathodic coupling of said component (1), without intermediate rinsing, in the same electrolyte or in a similar or equivalent electrolyte, said functional layer (3) being made of iron (5).
