The metal products do for plating coating metal cation cathode, formed in the metal surface coating reduction.
待镀的金属制品做阴极，镀层金属的阳离子在金属表面被还原形成镀层。
Simultaneously, a nondestructive chemical reaction (reduction) would proceed at the cathode, in most cases producing hydrogen gas on it.
同时，在阴极进行非破坏性反应(还原反应)，多数情况下在阴极产生氢气。
This article mainly describes the influences on the reduction results, such as: the electrode material, electric current density, acidity of cathode liquor and initial temperature of feed liquid.
本文主要考察了电极材料、电流密度、阴极液酸度及料液初始温度对还原效果的影响。
