基于软件模拟的固体物质氧化腐蚀过程研究

Study on Process of Solid Material Oxidation Corrosion based on Software Simulation

运用多物理场耦合有限元分析软件,对固体物质在氧气充足情况下的氧化腐蚀情况进行模拟,得到了某固体物质在某温度下清晰的氧化腐蚀过程。在模拟结果中,可提取的信息包括固体物质的体积、质量随时间的变化情况、由腐蚀引起的氧气浓度变化以及温度变化。此腐蚀模拟方法对于腐蚀环境下的材料力学性能研究有重大作用。

The simulation of solid material＇s oxidation corrosion in fully oxygen condition is carried out with the multi-physical finite element analysis software.The clear process of oxidation corrosion of a solid material in a certain temperature can be achieved.A lot of information can be extracted from the simulation results,such as the change of the mass and volume of the solid material,the changes of oxygen concentration and temperature caused by the corrosion along with time variation.The corrosion simulation method has a major role in the study on mechanical properties of materials under corrosive environment.
