Cold rolling, Raney-nickel-coated cathodes

Cold rolling, Raney-nickel-coated cathodes, 40 114... 

Although at least four different technologies [cold rolling, flame spraying, Zn and A1 melt dipping, cathodic deposition of Ni/Zn precursor alloys (76)] have been described, only cold rolling and cathodic deposition of precursor alloys are used for commercial production of Raney-nickel-coated cathodes.
