CORROSION RESISTANCE OF HOT ROLLED REBAR QUENCHED WITH A NEW CHEMICAL REAGENT
新型化学剂快速冷却热轧螺纹钢的防锈性能研究

The corrosion resistance of 20MnSi rebar,which was quenched with a new kind of chemical reagent FM,was studied.The results showed that a compact and smooth scale can form on the surface of the rebar,which can effectively protect the rebar against atmospheric corrosion,when this chemical reagent FM was used on the cooling process after rolling of rebar.According to the atmospheric exposure test,wet/dry cyclic accelerated corrosion test,salt spray accelerated corrosion test and electrochemical test,the corros...
