| 摘 要： | 利用自行设计的实验装置,研究了瓦特镍射流电沉积不同阳极喷嘴口径下电压与电流、电流密度、电流效率关系,以及阳极喷嘴口径对沉积层的金属分布的影响.研究发现:可用电流密度高达800A/dm2,沉积物呈圆柱形分布,沉积物直径几乎与相应的0.8,1.2,1.6mm阳极喷嘴口径一致.当喷嘴口径为1.6mm时电流效率为89.8%,而喷嘴口径为0.8mm时只有64.3%.

| Abstract: | A method of jet flow electrodeposition was established with watt nickel solution. The rela- tionship between voltage and current, current density and current efficiency, nozzle caliber and effect of anode nozzle caliber on metal distribution were investigated. The deposits were uniform, coherent even the current density higher than 800A/dm^2. The columnar deposit were got with diameters almost the same as nozzle caliber at 0.8, 1.2, 1.6mm. The current efficiency was strongly dependent on the nozzle caliber size. When nozzle caliber was 1.6mm, the current efficiency was 89.8%, nozzle caliber 0.8mm, the current efficiency only was 64.3%. |
