- 电镀作为一种广泛采用的表面处理方法，在处理复杂零件时常常遇到诸如膜层不均匀、表面缺陷等问题。本研究旨在针对此类问题进行内腔和外形复杂零件电镀仿真及优化研究。通过多离子迁移模型以及欧姆定律、拉普拉斯方程、泊松方程等公式建立了仿真模型，并针对模拟结果，进行了电镀工艺参数、工装的优化以及零件在镀槽中的排布调整。研究结果表明，优化的电镀工艺参数和工装的调整显著改善了内腔和外形复杂零件的电镀质量和效率，为电镀工艺提供了重要的理论指导。
- Abstract:
- Electroplating is a widely used surface treatment method, but it often encounters issues such as uneven distribution of coating layers and surface defects during the plating process of complex components with intricate inner cavities and outer shapes. The aim of this study is to conduct simulation and optimization of electroplating for complex internal and external parts in response to such issues. A simulation model was established using a multi-ion migration model and formulas such as Ohm’s law, Laplace’s equation, and Poisson’s equation. Based on simulation results, optimization of electroplating process parameters and fixture, as well as the adjustment of component layout in the plating tank are performed. The research results indicate that optimized electroplating process parameters and fixture adjustments significantly improve the plating quality and efficiency of complex inner cavity and outer shape components, providing valuable theoretical guidance for electroplating processes
