  • Why is it not permissible to have a power failure  during hard chrome plating?

    Why is it not permissible to have a power failure during hard chrome plating?

    Hard chrome additive application process, due to the hexavalent chromium layer is easy to passivate (trivalent chromium chromium plating layer in trivalent chromium chromium plating solution passivation is poor; metal chromium passivation coefficient as high as 0.74, second only to aluminum and titanium), therefore, plating is not allowed to be a very short time in the middle of the power outage (the requirements of the workpiece and the hanging device should be elastic contact, the hanging device and the cathode copper rod to ensure that the conductive is good).
