摘要：As magnetism and electricity are basic natural phenomena which are inextricably linked together, the connections between electric and anticorrosion properties exist objectively. Exploring the relationship between magnetism and corrosion prevention is significant but challenging. Through researching X-ZnO solid solution doped by magnetic metal (X = Fe, Co, Ni, Cu, and Mn), interesting and meaningful results emerge. First, the Cu-ZnO shows multistage self-assembly phenomenon, forming a pretty Rubik's cube structure. Second, the experiment results suggest that effects of multilayer shielding, electron transfer delay, and inducing electrolyte deflection synergistically contribute to the tremendous increase of anticorrosion performance. The supreme impedance pertained to Cu-ZnO coating, enhanced by 15 times compared to undoped ZnO after immersion in 3.50 wt % NaCl solution for 168 h. Particularly, the quantitative relationship between magnetic and anticorrosion properties is established. The formula derived from experimental data can guide the synthesis application of materials.
