摘要
目的研究军用车辆不同破损程度下的镀锌板腐蚀行为。方法以3.5%Na Cl溶液为实验介质,利用开路电位、电化学阻抗谱及动电位极化曲线技术进行研究。结果镀锌钢板的开路电位比基板低约0.3 V,镀层腐蚀速度随着破损率的增加逐渐增大,基板的腐蚀速度最低。结论镀锌层的腐蚀对破损试样基体起重要的保护作用。
Objective To study the corrosion behavior of galvanized plate of military vehicle with different damage rates. Methods The corrosion behavior was studied by the technology of open-circuit potential, EIS and potential-dynamic polarization in 3.5% NaCI solution. Results The open circuit potential of galvanized plate was about 0.3 V lower than the substrate, the corrosion rate increased gradually with the increase of the damage rate, and the substrate showed the lowest corrosion rate. Conclusion The corrosion of galvanized plate plays an important role in the protection of the damaged sample substrate against corrosion.
