| 摘 要： | 采用光电化学的方法研究了复合缓蚀剂对钢筋钝化膜的影响.结果表明复合缓蚀剂的加入没有改变钢筋钝化膜的晶体结构和电子性质,它仍然是无定形n型的半导体成相膜,但对抑制点蚀核的形成有明显作用,且对钝化膜的生长速度有加快作用,从而有可能使钝化膜的组成发生改变.

| Abstract: | An in situ photoelectrochemical study was made to compare passive films on rebar formed in simulated concrete pore solution with or without inhibitors. The results indicated that the crystal structure and electron property of passive film were not changed due to adding composite inhibitors. It was still a n type amorphous semiconductive film. But pitting nucleus initiation was inhibited obviously and the growth rate of passive film was increased by adding inhibitors so that the composition of the film might be changed. |
