    Abstract: Friction-reducing coating compositions and coated machine parts having a wearing surface provided with coatings of same. In one embodiment, the coating composition includes from 10 to 25 weight % molybdenum metal; from 55 to 70 weight % nickel alloy; and from 5 to 25 weight % chromium carbide Cr.sub.3 C.sub.2. In a second embodiment, the coating composition includes from 25 to 45 weight % molybdenum metal; from 45 to 60 weight % nickel alloy; and from 5 to 25 weight % of a hard substance selected from chromium metal, chromium carbide Cr.sub.23 C.sub.6 and molybdenum carbide Mo.sub.2 C. Preferably the nickel alloys contain from 73 to 95 weight % nickel and have a melting point below that of nickel metal. Preferably the friction-reducing coating is applied to a wearing surface by plasma flame spraying. These coatings impart excellent wear resistance to the wearing surface, while lowering wear of counter-running faces.

    Abstract: A circular disc shape case 11 includes a motor rotor chamber 12, a bearing chamber 13 and a gear chamber 14 piled sequentially and being communicated with each other. A suction port 15 is connected to the motor rotor chamber 12, and a discharge port 16 is connected to the gear chamber 14, which communicate with outside respectively. A rotating shaft 18 having an end positioned in the motor rotor chamber 13 and the other end extending to the gear chamber 14. A rotor 22 is fixed around the rotation shaft 18 in the motor rotor chamber 13. A first bearing 19 is provided for supporting the end of the rotating shaft 18 in radial and thrust directions. A second bearing 20 is provided in the bearing chamber 13 for supporting an intermediate portion of the rotating shaft 18 in radial direction. A trochoid gear 25 is provided in the gear chamber 14, having an outer rotor 26 and an inner rotor 27, which functions as a pump, taking in a fluid through the suction port pipe 15, and discharging the fluid from the discharge port 16.

    Abstract: A low-friction piston construction for use in an oil-fed cylinder bore with the piston skirt relieved to define lands that are coated with SFL (graphite, MoS.sub.2, BN, and a special expoxy resin). A method of making such piston construction including provision of asperities on the skirt wall onto which the SFL coating is thermally sprayed and formation of small pockets at the mouth of the asperities to additionally act as oil replenishing reservoirs. A method of using such piston construction in an engine which comprises provisions of a slightly increased gap between the piston and cylinder wall and formation of a transferred SFL coating from the piston to the cylinder wall resulting in two polished microsmooth mating coatings, each attractive to oil films.
