本文用恒电量微扰法研究了C33+对铝合金在0.1mol·1-1NaCI介质中的缓蚀机理及抗孔蚀性。结果表明：铝合金孔蚀诱导过程及其表面形成铈转化膜过程具有相同的电化学模式，电化学腐蚀速度控制步骤取决于钝化膜（转化膜）／溶液界面过程。Ce3+对铝金孔蚀的诱导期和发展期均有抑制作用，形成铈转化膜后，铝基表面阻抗大大提高，耐孔蚀性增强。
In this paper, the corrosion inhibition mechanism and anti-pitting property of C33 + on aluminum alloy in 0.1mol · 1-1NaCI media were studied by constant power perturbation method. The results show that the electrochemistry corrosion rate control step depends on the process of passivation film (conversion film) / solution interface during the process of pitting induction and the formation of cerium conversion coating on aluminum alloy. Ce3 + has inhibitory effect on the induction and development of pitting corrosion of aluminum alloy. After the formation of cerium conversion coating, the surface resistivity of Al-based alloy increases greatly, and the pitting corrosion resistance increases.
