Application Research of Comsol Multiphysics on Corrosion Protection

Comsol Multiphysics是一款为许多领域科研工作者和工程师提供仿真服务的多功能实用模拟软件。许多腐蚀研究者使用Comsol Multiphysics软件对腐蚀防护措施下金属表面的物理、化学变化进行数值计算，从微观尺度上还原腐蚀内部机制，以便于从宏观尺度上对防护措施的性能进行评价。本文介绍了Comsol Multiphysics软件近些年在腐蚀防护方法中的应用研究现状，综述了其在阴极保护、电镀保护及其它类型保护中的使用情况，阐述了其在腐蚀防护研究中起到的关键性作用，并对其在未来腐蚀研究中的应用前景提出了展望。 Comsol Multiphysics is a multi-functional and practical simulation software which can provide services for science researchers and engineers from many kinds of fields. Many corrosion re-searchers apply Comsol Multiphysics into numerical calculations of physical and chemical changes on metal surface under the measures of corrosion protection, and then restore internal corrosion mechanism from microscopic scale, so as to evaluate the performances of protective measures from macroscopic scale. This paper introduces the current application of Comsol Multiphysics about the corrosion protection methods in recent years, summarizes the situation of usage in cathode protection, electroplating protection and other types of protection, expounds the key role it plays in corrosion protection research, and puts forward prospects to its future application in the study of corrosion.
