galvanostatic polarization. These experiments were performed at a constant current density of 50 mA/cm2, which was adopted in a typical zinc tank house. Anodic potential variations of Pb, Cara-Pb and Pyra......
Polarization curves of zinc coatings with different Ce contents in 3.5% NaCl solution at 25 ℃ 从图9可知,随镀液中Ce含量增加,镀层极化曲线的阳极分支变化不大,而极化曲线的阴极分支则向着电流密度减小的方向移动,这说明Ce的添加主要抑制阴极反应.同时也注意到Zn-0.012Ce和Zn-0.2Ce的阴极...): 529-546.
