“锌克能”为碱性工艺，但克服了氢过电压的问题，能直接镀于铸铁表面上，沉积层均匀，可有效覆盖深凹部分区域。
The effect of non-ionic surface active substances on hydrogen overvoltage on Hg
聚氧乙烯型表面活性剂对汞电极上氢析出过程的影响
Modified ni-s_x cathode with low hydrogen overvoltage
改性低氢超电压镍-硫阴极
The cathode active material with low hydrogen evolution overvoltage was prepared by electroplating Ni_Sn alloy on the ferrous basic body.
在Fe基底材料上电镀NiSn合金制备低析氢过电位的阴极活性材料。
The catalytic hydrogen wave is ascribed to the fact that certain substances containing nitrogen or sulfur can diminish the hydrogen overvoltage and accelerate hydrogen ion discharge at more positive potential on the cathode.
催化氢波是指含硫，氮等元素的物质能够结合质子，从而降低氢在汞电极上的超电位，使氢在较正电位处还原。
