一个简单的模型描述了均匀和局部的腐蚀 我们使用介观元胞自动机（CA）类型的方法，该方法已被证明是研究粗糙金属-电解质界面的有力工具 该模型考虑了两种腐蚀动力学及其相对空间定位 两种形式的腐蚀动力学之间的竞争被证明可以重现几种类型的腐蚀形态，范围从狭窄的凹坑或较大的空腔到粗糙的表面 比较模拟和实验结果，提供对腐蚀前沿动力学和形态之间关系的见解 我们强调与 CA 相关的随机模拟。 (C) 2010 Elsevier Ltd 版权所有
A simple model describes uniform and localised corrosion We use a mesoscopic cellular automata (CA) type approach which has proved a powerful tool in the study of rough metal-electrolyte interfaces The model accounts for two corrosion kinetics and their relative spatial localisation The competition between the two forms of kinetics of corrosion is shown to reproduce several types of morphology of corrosion ranging from narrow pits or larger cavities to rough surfaces Simulation and experimental results are compared providing insight on the relation between kinetics and morphologies of the corrosion front We emphasize the importance of stochastic simulations in relation to CA.
