| description | In the actual soil environment, due to the unpredictable characteristics of metal pitting corrosion. Therefore, in this study, soil composed of different concentrations of corrosion medium was used for the mental corrosion test, and the experimental results of single ion and multiple ions were compared. At the same time, the corrosion behavior of metals is introduced in combination with the mathematical model of unsteady diffusion. In addition, the cellular automata model verification method is used to study the comparison and verification of the diffusion growth model of the model corrosion pit in different iteration steps under the discrete mathematical model. The results show that the growth and diffusion trend of corrosion pits controlled by the concentration of SO42-, HCO3–, and Cl- is consistent basically with the law reflected by cellular automata. |
