Development of Ultrafine abrasive pellets Applying Electrophoretic deposition

本文描述了利用超细磨料电泳沉积可以制备出高度均匀的微球，用微球研磨硬质和脆性材料都可以获得小于10nm -v的光滑表面。实现微小的晶粒深度切削是磨削获得光滑表面的重要特征。因此，需要应用由直径为10至20nm的超细磨料组成的砂轮。带负电荷的超细磨料可以通过电泳沉积均匀地沉积在阳极上。应用该技术可以方便地制作出均匀的超细砂轮。在磨削过程中，高度均匀的树脂轮具有合适的结合强度，可实现粒度自锐。因此，砂轮可以产生一个光滑的表面，防止屑加载和晶粒钝化的发生。

In this report, it is described that highly homogeneous pellets can be fabricated by applying electrophoretic deposition of ultrafine abrasives, and a smooth surface of less than 10nmp-v can be obtained for both hard and brittle materials by grinding with the pellets. The realization of a minute grain depth of cut is an important feature for obtaining a smooth surface by grinding. Hence it is desirable to apply a grinding wheel composed of ultrafine abrasives of diameters of 10 to 20nm. Ultrafine abrasives which are negatively charged can be deposited homogeneously on an anode by applying electrophoretic deposition. It is easy to fabricate a homogeneous ultrafine grinding wheel by applying this technique. Highly homogeneous resinoid wheel with suitable bonding strength results in grain-sized self-sharpening in a grinding process. As a result, the grinding wheel can yield a smooth surface by preventing the occurrence of swarf loading and grain dulling.
