ELECTRODEPOSITION BEHAVIOR OF Mn WITH Ni IN ACIDIC SULFATE SOLUTIONS

JI, DAN; LE, XIAWEN; ZHONG, QINGDONG; ZHOU, QIONGYU - In: Surface Review and Letters (SRL) 21 (2014) 06, pp. 1450083-1

The influence of Mn2+/Ni2+ mole ratio in electrolytes on the Ni–Mn alloy deposits was studied. The electrodeposition mechanism of Mn with Ni is analyzed by the cyclic voltammogram (CV) and an "induced co-deposition" mechanism is proposed for Ni–Mn alloy electrodeposition. The results show...
