尽管一般是通过液态锌蘸洗钢铁来镀锌，有时候也会用电解的方法，在电镀镍和铜时就通常使用电镀。

Though galvanisation is often done by dipping steel in liquid zinc, it is sometimes done by electrolysis—nickel and copper plating are normally done this way.

而所谓电镀锌就是利用电解，在制件表面形成均匀、致密、结合良好的金属或合金沉积层的过程。

And the so-called electro galvanizing is the use of electrolysis, the formation of uniform, dense, combined with the process of metal or alloy deposit on the surface of workpiece is good.
