Abstract
PURPOSE: To prevent the disengagement of a piston ring during power supplying by forming a concave groove on the inside peripheral surface of the piston ring and fitting a power supply contact into this.
CONSTITUTION: At the time of plating the top and under surfaces A, B of a piston ring 1, a concave groove 7 is provided to its inside peripheral surfaces to improve the contact with the end 8 of a cathode contact means 3 holding the piston ring 1 in plating soln. This piston ring 1 is held in the plating soln. 5 by the contact means 3, and with this as cathode, it is dipped for a fixed time, after which the power is supplied by an electric power source 2, whereby plating is performed. Since the end 8 of the contact means 3 is held in place in the concave groove 7 of the inside peripheral surface D of the piston ring 1, the disengagement during handling does not occur.
