The Process of Zinc Immersion on the Surface of Mg-Li Alloy

Abstract

The process of zinc immersion for Mg-Li alloy is researched in this paper. Through orthogonal experiments, the optimum process parameters are obtained. The microstructure and the composition of the Zn-dipped coating were measured with SEM, XRD, EDS and electrochemical testing. Results show that, the optimum process parameters are: concentration of main salt (ZnSO4) is 40g/L; solution temperature is 60°C; dipping time is 5min. In addition, dipping time is the most influential factor, then is solution temperature, the last is the concentration of main salt.
