| Abstract: |
| This paper proposes a method of simulating corrosion morphology by the cellular automatic machine approach. The procedure is based on a roundness grid to simulate the development of corrosion pits, solving the problem of singularity in the development of each direction under a polygonal grid. By constructing a mathematical model with this method, the single etch, the crevice width, and environmental factors simulate pits of pitting-type crevice corrosion. And the evolution pattern of corrosion damage degree of multiple etch pits on annular areas such as rings and shims is also initially explored. |
