  • Composite plating film and a process for forming the same
    Patent number: 7022419
    Abstract: A composite nickel and copper alloy plating film (3) containing nickel and copper. Nickel is of high wear resistance and a nickel alloy improves the wear resistance of the film. Copper is of high resistance of the film. The film may further contain self-lubricating particles and hard particles which ensure its wear resistance and lubricating property to a further extent.

  • Magnetostrictive coat forming method, magnetostrictive torque sensor manufacturing method, and electric power steering apparatus employing the sensor
    Publication number: 20040226384
    Abstract: For forming an annular magnetostrictive coat on an outer peripheral surface of a rotational shaft associated with a magnetostrictive torque sensor, a magnetostrictive-coat forming method comprises a step of fitting a cylindrical masking jig over the outer peripheral surface of the rotational shaft and securing the masking jig to the outer peripheral surface, a step of placing the rotational shaft in a plating tank to thereby form the magnetostrictive coat by plating on the outer peripheral surface, and a step of detaching the masking jig from the rotational shaft.

  • Method and apparatus for applying composite plating on hollow member
    Patent number: 5516417
    Abstract: A hollow member whose internal surface is to be applied with composite plating is held in a condition in which a generatrix of the internal surface extends vertically. An electrode is inserted into the hollow member with a predetermined clearance to the internal surface of the hollow member. A composite plating liquid supply passage has a discharge opening which is in communication with an opening at a lower end of the hollow member. A gas is entrained in a form of bubbles into a composite plating liquid which is supplied into the clearance through the supply passage.
