针对电沉积工艺中沉积层表面和边缘容易产生积瘤、毛刺等缺陷,在电沉积过程中加入了摩擦辅助装置,并与快速成形技术相结合,提出了一种基于离散/堆积原理的摩擦电沉积快速成形技术,用于简单、快捷、低成本地直接成形金属零件。通过快速成形金属铜制件试验表明：紧贴阴极表面的实时动态的撞击和摩擦,能有效地去除沉积层表面的吸附气泡和积瘤,获得表面平整光亮的电铸层;摩擦电沉积快速成形技术能够综合快速成形和电铸技术的优点,有效降低设备复杂度和零件成本,直接快速制造出形状复杂、结构致密、组织均匀的精密金属零件。
Because of the defects such as the easily produced tumors and the burrs on the electrodeposition surface during the electrodeposition process, friction assistive device was added in it and a kind of electrodeposition rapid prototyping technology that based on discrete/accumulation theory was proposed. The new technology is the core principle of rapid prototyping technology and can directly deform the metal parts simply, quickly and with low cost. Copper electrodeposition experiments show that the real-time dynamic friction closing to the cathode surface can effectively remove adsorption bubbles and tumors of the electrodeposition surface and obtain a smooth and bright surface for the electroforming layer; the rapid prototyping of friction electrodeposition technology takes the advantages of both the electroforming technology and the rapid prototyping technology, so the complexity of equipments and the cost of the parts can be effectively reduced and the precise metal parts with complex shapes, compact and homogeneous structure can be directly and quickly created.
