| Abstract: | The factors affected the preparation of pulse electrochemical nickel by high current density were studied.The optimum technological conditions for 35℃electrolysis were obtained: in supporting electrolyte,electrolyte dosage of ammonium sulfate was 35～45g·L-1,and the distance between anode and cathode was 4～6cm.Additive amount: concentration of chloride 3.0 mg·L-1,concentration of urea 0.25mg·L-1,concentration of glycerin 0.5 mg·L-1.The granularity distributing,particle size and appearence characteristics of electrolysis products were analyzed by laser particle size analyzer scanning electron microscope. |
