摘要: 本文提出用三相线界面区参数描述液相分散程度,研究了三相线界面区阴极过程特征,建立三相线界面区阴极过程模型.并探讨了液相覆盖区阴极极限电流和三相线区状态的相关性,证实了模型计算与实验数据一致性.进而用三相线界面区阴极过程模型分析液相分散程度对大气以及砂土体系腐蚀行为的影响.

Abstract: Liquid dispersion,described by the parameters of gas/liquid/solid three-phase boundary(TPB) zone of dispersed liquid on a metal surface,is an important property of liquid state influencing corrosion behavior of metals in gas/liquid/solid multiphase corrosion systems.In our paper,the characterisation of cathodic oxygen reduction process in TPB zone was discussed,and a model describing the cathodic process of TPB zone was developed.On this basis,the relationship between the cathodic limiting current and the TPB parameters was studied,and the simulation results were in good agreement with the experimental data.The role of liquid dispersion in atmospheric and sandy soil corrosion systems was also simulated.

Key words: liquid dispersion, gas/liquid/solid multiphase corrosion systems, three-phase boundary, cathodic process, modeling
