Zinc alloy coatings can be obtained from suitable range of bath, and it has attracted a great attention due to their unique high corrosion resistance, low hydrogen brittleness and chemical stability.
The result indicated the current of hydrogen permeation from chloride bath was smaller than that from sulfate-chloride bath.
结果表明，氯化物体系比硫酸盐-氯化物混合体系渗氢电流小。
