Complexing agent on the surface of magnesium alloy plating of Ni-B Alloy

摘要

In this paper, different concentrations of complexing agent affect the surface of magnesium alloy plating of Ni-B alloy. Ethylenediamine has influence on the chemical plating of Ni-B alloy plating rate, coating morphology, corrosion resistance, and determines the best complexing agent concentration. The results show that when the ethylenediamine concentration is 160mg/L, the plating rate is maximum, the coating uniformity, structure compact, and good corrosion resistance.
