The salt spray resistance time
Electro-galvanizing is the electro-chemical deposition of a zinc layer on a metal surface, due to its relatively thin coating, the salt spray test time is relatively short. Electro-galvanized layers without additional treatment can withstand a salt spray test of 24-36 hours;

The solutions to metal hydrogen embrittlement in electroplating
Improve the purity of metal materials: Reducing the impurity content in metal materials can effectively reduce the chance of metal absorbing hydrogen. In the process of metal preparation, heating treatment, smelting and other methods can be used to improve the purity of the metal.
