A layer of hot-dipped galvanizing causes a considerable reduction in the fatigue strength. 热浸镀锌层引起疲劳强度的显著降低。
The research in flux is mainly to change the original double hot dip coating technique, and change the first hot-dip galvanizing into electrolyzing flux. 对于助镀剂的研究主要是改变原有的双热浸镀工艺，改第一次热浸镀锌为电解助镀。
