Three-Dimensional Cellular Automata Model of Uniform Corrosion for Aluminium Alloy

The corrosion damage is easy to be formed on the surface of a metal structure in the corrosion environment, then the structural mechanical properties are degraded. For this purpose, the cellular automata method was adopted to simulate the uniform corrosion damage behavior of aluminium alloy in this paper. The uniform corrosion of aluminium alloy surfaces is simulated in complex corrosive environments and different concentration of corrosion solution. The forming processes of corrosion and the changed rules under different concentration of corrosion solution c and ambient temperature T are all obtained. It was shown that with the increasing concentration of corrosion c and the ambient temperature T, the number of corrosion cells increased, and the number of corrosion cells presents an approximate power function of etching time t.
