请问有谁了解Galfan hot dipping的时候使用氯化铵出去氧层是什么原理吗?

我现在在做Glafan (95%Zn, 5%Al)合金的hot dipping 镀膜。但是基地钢管上总是会有一层氧化物,直接导致蘸上去的金属脱落。看到有文献里说氯化锌和氯化铵的混合物可以除去这层薄膜。请问有哪位了解这是什么原理吗?这个可以自己配吗? 谢谢! Fluxing Finally, the steel is dipped in the flux. The purpose of the flux is to clean the steel of all oxidation developed since the pickling of the steel and to create a protective coating to prevent any oxidation before entering the galvanizing kettle. One type of flux is contained in a separate tank, is slightly acidic, and contains a combination of zinc chloride and ammonium chloride. Another type of flux, top flux, floats on top of the liquid zinc in the galvanizing kettle, but serves the same purpose. After degreasing, pickling, and fluxing, the surface of the steel is a near white metal clean, completely free of any oxides or other contaminants that might inhibit the reaction of the iron and molten zinc in the galvanizing kettle.
