| 摘 要： | 选择柠檬酸型镀液，用脉冲电镀法成功制备纳米锌镀层;并用电化学法和随机法等研究纳米化对纯锌点蚀行为的影响.结果表明：纳米锌和铸态锌的点蚀击破电位均服从正态分布;纳米化增加了纯锌点蚀击破电位对电位扫描速度的敏感性，使纯锌的点蚀产生类型由B1（parallel）型转为B2（series）型，并能抑制纯锌的点蚀生长.

| Abstract: | Pulse electrodeposition was used to deposit nanocrystalline(NC)zinc coating on A3 steel from a citric acid bath.The grain size and preferential orientation of grains of the coatings were determined by X-ray diffraction.Pitting corrosion behavior of the NC zinc coating was investigated by using potentiostatic and potentiodynamic polarization methods in 0.5 mol/L NaCl(pH=12)solution.Pitting corrosion behavior was characterized by pitting potential,pitting initiation time as well as the stable pit growth rate,... |
