中文摘要：

沉积层均匀性控制影响叠层模板电铸成形的关键问题。本文中提出了一种辅助磨削脉冲电沉积成形技术,设计了基于其原理的工艺设备。试验方法即将硬质陶瓷粒子引入于电极之间,通过电铸阴极的旋转带动,硬质粒子（陶瓷珠）在电沉积过程中不断摩擦、撞击阴极表面,以期即时消除沉积层表面由于电流分布不均引起的边缘效应。通过表面形貌观察及铸层高度的测量统计,将传统与新型微电铸工艺制备的试样进行了对比。结果表明：硬质粒子可有效阻止杂质的吸附,避免毛刺、积瘤等表面缺陷的产生,能够获得良好的铸层均匀性,表面粗糙度可达0.253μm。表明硬质粒子摩擦在叠层电铸成形中具有较好的实用价值。

英文摘要：

Focusing on the deposit uniformity control that plays a key role in the laminated template electroforming,a friction-assisted pulsed electrodepositing technology was developed in this paper as well as its experimental ae- vice. According to the experimental method, a number of hard particles （ ceramic beads） fill in space between the electrodes and are propelled by mandrel＇s rotating movement to allow continuous impinging and grinding to the cath- ode surface, as an effort to instantaneously eliminating boundary effect that is caused by uneven current distribu- tion. In comparison of the finish surface morphology and deposit thickness among the samples obtained respectively by traditional and new ways, the experimental results showed that the assistant friction could effectively remove the sediment and tumor along surface and provide a relatively fiat layer with Ra 0.253/zm. It indicates that the hard- particle-friction has highly practical value in the prototyping of laminated electroforming.
