| 摘 要： | 利用干湿交替加速腐蚀实验和电化学实验研究了实验钢在模拟工业大气环境下的腐蚀演化行为.结果表明,在腐蚀初期腐蚀速度随循环周期的增加而增大,在后期随循环周期的增加而降低,耐候钢的腐蚀速度与SPA-H钢相当但低于16Mn钢.在腐蚀初期,细晶粒耐候钢比粗晶粒腐蚀速度快,在后期腐蚀速度基本一致.耐候钢锈层分为内外两层,内锈层致密主要由α-FeOOH和少量γ-Fe2O3组成,晶粒尺寸对腐蚀产物的组成影响不大.16Mn钢锈层主要由α-FeOOH,γ-Fe2O3和Fe3O4组成.在腐蚀后期,Cu的作用使耐候钢的耐腐蚀性能优于16Mn钢.电化学实验表明,腐蚀产物促进阴极过程,抑制阳极过程.细晶粒有利于保护性内锈...

| Abstract: | Corrosion evolution of Mn-Cu weathering steels in a simulated industrial atmosphere environment was studied by wet/dry cyclic accelerated corrosion test and electrochemical test.The results showed that the corrosion rate increases with the wet/dry cycles in the initial stage of the test and decreases in the latter stage of the test.The corrosion rate of weathering steel is near to SPA-H steel and lower than that of 16Mn steel.In the early,the corrosion rate of fine grain weathering steel is faster than that... |
