Chromium plating part manufacturing method and chromium plating apparatus

摘要

This method of manufacturing a chrome-plated component includes a chrome-plated layer in which a plurality of workpieces are immersed in a chrome-plating bath, plating is performed using a pulse current, and cracks having compressive residual stress on the surfaces of the plurality of workpieces are suppressed. To precipitate. During the pulse current application quiescent time, a direct current having a current density in a range having a compressive residual stress is superimposed on the chromium plating layer from the plating deposition lower limit current density.
