Simulation and optimization of hard anodic oxidation of internal cavity parts
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.
