摘要
电镀实验是电解原理应用的重要案例,通过实验不仅要获得定性的感性认知,还应该获得定量的理性数据。针对电镀铜实验,通过改变铜离子浓度、pH、电解时间、电解电压和电解温度等因素,探究其对镀层厚度、均匀性和致密性等性质的影响,在电解原理的基础上分析其形成机制,从而确定了电镀铜较适宜的操作条件,以此为学生开展电镀实验提供参考案例与研究思路。
Electroplating experiment is an important case of the application of electrolysis principle. Through experiments, not only qualitative sensibility recognition, but also quantitative rational data should be obtained. In this paper, the effects of copper ion concentration, pH, electrolysis time, electrolysis voltage and electrolysis temperature on the properties of plating thickness, uniformity and compactness were investigated for electroplating copper experiments. The mechanism of formation was analyzed on the basis of the electrolysis principle and determined the suitable operating conditions for electroplating copper. It also provided reference cases and research ideas for students to carry out electroplating experiments.
