Patent ID: 8173004

Claim:
A method of manufacturing a chromium plated article comprising: immersing a plurality of works in a chromium plating bath; and depositing a chromium layer having a desired compressive residual stress on a surface of each of the works by using a pulse current; wherein a waveform of the pulse current supplied to each of the works is made substantially uniform irrespective of the works by adjusting inductance of a wiring from a pulse power source to each of the works, wherein the works are disposed in an apparatus which comprises a plurality of anodes and a plurality of cathodes disposed in such a manner as to correspond to each of the plurality of works, an anode holding body which is connected sequentially to the plurality of anodes and is connected to a positive pole of a pulse power source, and a cathode holding body which is connected sequentially to the plurality of cathodes and is connected to a negative pole of the pulse power source; and wherein chromium plating is performed, with the pulse power source connected to a middle part of one of the anode holding body and the cathode holding body, and the pulse power source connected to both ends of the other of the anode holding body and the cathode holding body, and wherein at least one of the anode holding body and the cathode holding body has inductances of wiring between adjacent ones of the plurality of the anodes or the plurality of the cathodes, which increase with increasing distance from a connection with the pulse power source.
