PURPOSE:To form a wear resistant film having fine luster by electroless plating at a high speed by using a body to be plated as the cathode in an electroless nickel plating bath and supplying a prescribed pulsating current so as to increase the catalytic activity on the cathode side. CONSTITUTION:The surface of a nonmetallic material is coated with a metallic film and the coated material is immersed in an electroless nickel plating bath contg. a nickel salt and a hypophosphite. The body to be plated is use as the cathode and a pulsating current having 0.1-100msec pulse length and suspension time is supplied at 0.1-3A/dm<2> average current density to form an Ni-P alloy film on the surface of the body to be plated. |
