The synergistic effect of Cu and Mn is listed as follows:(1) On improving the structure of rust layer, addition of Cu and Mn can reduce cracks and pores in rust layer;(2) On altering the composition of rust, it can increase the amount of Fe3O4 and γ-FeOOH, while decrease that of β-FeOOH;(3) On the chemical state of alloying elements and selectivity of rust layer, it mainly convert the anion selectivity to canoed selectivity;(4) On the electrochemical aspect, it can decrease the anode current density and increase the corrosion potential of steel.

Cu、Mn的协同作用主要体现在以下几个方面：在改善锈层结构方面，主要是减少锈层中的裂纹与孔洞，提高锈层与基体的结合强度；在改变锈层组成方面，增加Fe3O4和γ-FeOOH的含量，降低β-FeOOH的含量；在元素化学状态与离子选择性方面，促使锈层由阴离子选择性转变为阳离子选择性，抑制Cl-的渗透；在电化学方面，大幅度降低阳极电流密度，提高钢基体的自腐蚀电位。
