摘要： PURPOSE:To decrease the vane wear generated in relation to the sliding surfaces between the cylinder block inside surface and a vane groove provided in a rotor by furnishing an ion plating layer chiefly containing Cr and N over the outer surface of the wane which is inserted with possibility of emerging and retracting from/in the vane groove. CONSTITUTION:A front and a rear side-plate 2a, 2b are fixed to the front and rear of a cylinder block 1, and a compressor body 3 is formed. A cylindrical rotor 4 is accommodated in the compressor body 3, and the steel shaft 5 of this rotor 4 is supported on the two side-plates 2a, 2b by bearings 6a, 6b. Vane 8 is inserted in a vane groove 7 provided in the rotor 4. Therein an ion plating layer chiefly containing Cr and N is installed over the outer surface of the vane 8. This permits decreasing the wear of vane 8 generated in relation to the sliding surfaces between the inside surface of the cylinder block 1 and the vane groove 7.

摘要： PURPOSE:To provide the electroplating method capable of suppressing the generation of deformation and residual strains in a metallic material to be plated and forming a plating layer having a good adhesion property through an easy pretreatment. CONSTITUTION:This electroplating method includes a stage for degreasing a metallic surface made of aluminum or aluminum alloy by electrolytic washing, a stage for acidically activating the metallic surface rotating in the state of making friction contact with an anode body by electrolytic washing after the degreasing, a stage for forming an under coating layer by applying nickel plating to the metallic surface rotating in the state of making friction contact with the anode body after the acidic activation and a stage for forming a wear resistant outer layer on the under coating layer of the metallic surface. The metallic surface is clegreased and acidically activated and thereafter, the nickel plating liquid is electrodeposited thereon in the state of bringing the anode body into friction contact with the metallic surface under rotation and, therefore, the activation of the electrodeposited surface is accelerated and the oxide layer of the metallic surface is sufficiently removed. In addition, the nickel is strongly electrodeposited on the metallic surface and the under coating layer having high adhesive force is formed thereon.

摘要： PURPOSE:To provide a piston ring favourable in initial fittingness to a cylinder and excellent in abrasion resistance. CONSTITUTION:A piston ring for an internal combustion engine has a doubly- structured film consisting of a chrome nitride layer 2 formed by ion plating and a chrome oxide particulate dispersed cobalt-nickel-phosphorus alloy layer formed on the chrome nitride layer 2 at least on its outer peripheral slide surface of a piston ring parent material 1.

摘要： PURPOSE:To obtain a sliding member excellent in wear resistance and seizing resistance by forming an iron-chromium allay plating layer in which hard grains are dispersed into a base metal and executing ion nitriding treatment. CONSTITUTION:On the sliding face of the base metal, a compositely dispersed plating layer in which, in the alloy matrix, by volume, 5 to 30% hard grains having 0.5 to 10mum average grain size and 5 to 20% lubricant grains having 5 to 20mum average grain size are dispersed is formed. Next, the surface of the base metal is subjected to ion nitriding treatment. In this way, the sliding member excellent in wear resistance and seizing resistance and small in the wear of the mating member can be obtd.

摘要： PURPOSE:To provide an aluminium alloy-made piston for an internal combustion engine, excellent in abrasion resistance in a ring groove, baking resistance and heat resistance and abrasion resistance and scuffing resistance of a skirt part. CONSTITUTION:An aluminium alloy-made pistion of an internal compostion engine is constructed in such a way that an alloy plated layer 6 made of nickel, boron and tungsten is formed on at least the front surface of a ring groove 2 in the part closest to the head side, and a composite plated layer 7 made of an iron-group, a nickel-group or a cobalt-group wherein solid lubricant particles are dispersed is formed on at least the outermost layer of a skirt part 5. Preferably, an alloy plated layer 6' made of nickel, born and tungsten is formed on the lower layer of the composite plated layer 7 of the skirt part 5.
