摘　　要：铝合金硬质阳极氧化是常用的表面处理工艺,该工艺通过形成氧化膜来增强铝合金的耐腐蚀性、硬度和耐磨性。然而,在处理具有复杂内腔和外形状的零件时,传统工艺方法往往难以满足工艺要求,而仿真技术将在此方面发挥至关重要的作用。本文采用了仿真计算结果来指导工艺参数的优化和工装设计,并进行了试制验证。结果表明,通过优化硬质阳极氧化工艺参数和工装设计,成功地解决了工件因膜厚不均而导致的“烧焦”问题,并大幅提升了膜层的质量和膜厚分布的均匀性。仿真结果的准确性高,为工艺优化提供了可靠的依据。Aluminum alloy hard anodic oxidation is a commonly used surface treatment which can enhance the corrosion resistance,hardness,and wear resistance of aluminum alloys by forming an oxide film.However,when dealing with parts with complex internal cavities and external shapes,traditional processing methods may be difficult to meet the process requirements,and simulation technology will play a crucial role in this regard.In this paper,the results of simulation calculations were used to guide the optimization of process parameters and tooling design,trial production was conducted for verification.The results showed that the optimized hard anodic oxidation process parameters and tooling design successfully solved the problem of"burning"caused by uneven film thickness and significantly improved the quality of the film layer and the uniformity of film thickness distribution.The accuracy of the simulation results is high,providing a reliable basis for process optimization.
