Abstract (en)
Raney-nickel coated cathodes are made by plasma spraying a nickel/aluminum composition containing 56 to 59% by wt. nickel onto an electrically conductive cathode substrate, and activating the coated substance by leaching aluminum from the coating with caustic. The activated cathode is especially useful in chloralkali processes, as it operates at low hydrogen overvoltage, and is durable against spalling and flaking.
