摘要:

采用失重分析、X射线衍射分析、扫描电镜分析及电化学测试分析方法对Q235碳钢在模拟海洋工业大气环境中的初期腐蚀历程和机理开展深入研究,并着重探究了不同比例SO₂和Cl^-的协同效应对碳钢初期腐蚀行为机制的影响。结果表明,Q235碳钢在模拟海洋工业大气环境中的初期腐蚀呈现由加速过程向减速过程转化的特点,且加速过程的腐蚀动力学仍遵循幂函数规律D=Atⁿ;腐蚀24 h后,腐蚀产物呈现双层结构,即疏松的外层和相对致密的内层。SO₂和Cl^-的协同效应会加速碳钢的腐蚀,但二者比例的变化对碳钢腐蚀失重影响并不明显,也没有改变腐蚀产物成分,SO₂促使碳钢腐蚀形态趋向于均匀腐蚀。

Abstract：

Carbon steels as common structural material have been widely used for basic facilities with the development of the city. In these service environments, carbon steel would inevitably encounter the atmospheric corrosion. Especially, the corrosion of carbon steels exposed to coastal-industrial atmosphere is very outstanding. However, the initial corrosion mechanism of carbon steel subjected to coastal-industrial environment still need to be clarified, which would be vital for predicating the subsequent corrosion process. In addition, although many scholars studied the synergism of SO₂ and Cl^-, which obviously accelerates the corrosion of steel and reduces its service life, there is few research about the effect of the synergism of SO₂ and Cl^- (in different proportion) on the early corrosion behavior of the carbon steel. Therefore, it is of great importance to investigate the initial corrosion mechanism of carbon steel and the effect of the synergism of SO₂ and Cl^- (in different proportion) in the coastal-industrial atmosphere. In present work, the initial corrosion behavior of Q235 carbon steel exposed to a simulated coastal-industrial atmosphere has been studied by weight loss, XRD, SEM and electrochemical measurements. Also, the effect of the synergism of SO₂ and Cl^- (in different proportion) on the early corrosion behavior of Q235 car bon steel has been investigated. The results indicate that the initial corrosion behavior of carbon steel exposed to a simulated coastal-industrial atmosphere presented a transition from corrosion acceleration to deceleration, and the kinetics of accelerated corrosion process followed the empirical equation D=Atⁿ. A double-layered corrosion product was formed on the surface of carbon steel after 24 h: the loose outer layer and relative dense inner layer; the synergistic effect between SO₂ and Cl^- accelerated the corrosion of carbon steel. However, the change in the ratio of SO₂ and Cl^- had no significant effect on the corrosion loss of carbon steel, and had not changed the composition of corrosion products formed on carbon steel surface. SO₂ caused the corrosion morphology of carbon steel to tend to uniform corrosion.

Key words： carbon steel atmospheric corrosion synergism
