中文摘要:
      利用COMSOL Multiphysics对超临界流体电铸耦合场进行数值模拟,研究分析电流密度分布和电铸层生长规律,并且试验测试与验证;同时对超临界流体镍纳米金刚石复合镀层的表面形貌和显微硬度进行研究和探讨。结果表明阴极边缘处电流密度远高于阴极中间部分,电铸层生长情况与电流密度分布较为吻合,电铸层中部厚度预测值的误差较小;电铸层显微硬度最大可达951.47HV,比普通情况下复合铸层提高80%;制备的复合电铸层表面平整,组织致密。

英文摘要:
      : The coupling field of electrodepositing process under the supercritical fluid was simulated by COMSOL Multiphysics software to study the distribution of the current density and the growth of the electrodepositing coating which was verified by the experimental supercritical composite electrodepositing coating. Simultaneously the surface morphology and microhardness of the experimental supercritical nickel-diamond electrodepositing coating were studied and discussed. The results show that the current density on cathodic edge is much higher than that of the middle section and the predicted growth of the electrodepositing coating accords with current density distribution. The error between predicted and experimental thickness of the central supercritical electrodepositing coating is smaller. The biggest microhardness of the composite supercritical electrodepositing coating can reach 951.47HV(200g), a figure that is 80% higher than that of ordinary composite electrodepositing coating. The supercritical composite electrodepositing coating has smooth surface and compact structure.
