Abstract

The electrochemical behavior of Zn Ni alloy codeposition and concomitant hydrogen evolution have been studied in the chloride ammonia solution through the d c electroplating method. Under the condition of the applied cathodic current density of 2A/dm 2 , the AC impedance spectra have been measured. An equivalent circuit has been presented for the impedance study on the alloy codeposition.
