摘　　要：为了研究离子液体中复杂镀件的电镀层厚度分布与阳极和镀件形状的关系,本文设计了以铝板为象形阳极、镀件为阴极的一整套电镀铝装置。建立了电镀装置的CAD结构图,并使用有限元软件COMSOL进行模拟分析,给出了电流和电位分布、镀层厚度分布。结果表明:在电流密度100 A/m^2,电镀时间1 h时,可以在该镀件表面得到厚度均匀的铝镀层,边缘厚度为20μm左右。To study the relationship between the plating layer thickness distribution of complex parts electroplated by the hieroglyphic anode method and the shape of electroplated parts in ionic liquids,a complete set of electroplated aluminum equipment was designed in which an aluminum plate was used as the hieroglyphics anode and the work piece was used as the cathode.The computer-aided design structure diagram of the electroplating device was established,and the finite element software COMSOL was used to simulate and analyze it.The current and potential distribution and the thickness distribution of the coating were obtained.When the applied current density was 100 A/m^2 and the plating time was 1 h,the uniform thickness of aluminum coating could be plated on the surface of magnesium substrates,with an edge thickness of about 20μm.
