镁合金表面聚丙烯酸酯/氧化锌涂层的制备及耐腐蚀性能研究
Research on Preparation and Corrosion Resistance of Polyacrylate/Zinc Oxide Coating on Magnesium Alloy Surface
摘要
Abstract
A polyacrylate/zinc oxide coating was coated on the surface of magnesium alloy,and the effect of varying ZnO content in the coating on the corrosion resistance of magnesium alloy was investigated.Firstly,the hydrogen evolution rate,electrochemical impedance and polarization potential of the magnesium alloy coating in 3.5 wt％ NaCl solution were tested by hydrogen evolution test and electrochemical test.Then,the surface morphology,element composition and distribution of magnesium alloy coating before and after corrosion were characterized by scanning electron microscopy(SEM)and energy dispersive spectroscopy(EDS).The results show that compared with the AZ91D magnesium alloy substrate,the coating has a better protective effect on the magnesium alloy.关键词
