摘要
改变占空比、频率、电流密度,探讨脉冲电流对电解金属锰电流效率的影响规律,并与直流电解金属锰进行比较。占空比为0.5、频率为100Hz、电流密度为400A/m2时脉冲电解金属锰的电流效率最高,达到82.1%。在相同电流密度条件下,脉冲电解金属锰的电耗比直流电解金属锰低38.0%。通过XRD、SEM对电解金属锰层进行表征,结果表明:脉冲电解金属锰的沉积层更加平整光滑,颗粒的形貌更加均匀、细致及紧密,成分更纯净。
The duty ratio, frequency, current density were adjusted to study the influence of pulse current（PC）on manganese electrodeposition. The PC electrodeposition of manganese was compared with direct current（DC）elec- trodeposition. The current efficiency achieved 82.1% of conditions duty ratio 0.5, frequency 100 Hz and current density 400 A/m2. Under the same current density, the power consumption of PC electrodeposition was 38.0% lower than DC electrodeposition. The deposit was analyzed with X-Ray Diffraction（XRD）. The morphology of deposit was characterized by scanning electron microscope（SEM）. The results indicated that the manganese de- posit of PC electrodeposition was more uniform, closer and more pure.
