镀铝件结构与镀铝层膜厚的关系研究

Research on the Relationship of the Aluminum Plates and the Thickness of Aluminum Coating

摘要: 本文针对汽车车灯镀铝工艺，研究了镀铝件结构与镀铝层膜厚之间的关系这一问题。首先对长方体、楔形、锥形以及梯形这四种结构的模型，做了膜厚测试实验，然后引入立体角的概念表征几何体的结构特征，通过利用CATIA软件计算出对应的膜厚测试点的立体角，利用数据分析软件MINITAB，提出了膜厚与结构的关系表达式。最后，通过数值算例验证了本文结论的有效性。

Abstract: This paper investigates the relationship between the structure of aluminum plates and the thick-ness of aluminum coating for automobile lamps. Firstly, four models with different structure are adopted to test the film thickness. Then, on the basis of the solid angle method, the structural fea-tures of geometry are described. And then, based on the CTAIA and MINITAB, the expression of film thickness and structure is given. Finally, the numerical simulation example illustrates the ef-fectiveness of the results presented in this paper.
