“…Moreover, ordinary diamonds often expose only one large cutting edge after being prepared into abrasive tool, and the selfsharpening property of diamonds is poor. During precision machining, the grinding stress of ordinary diamonds is concentrated, and the surface of the workpiece is severely scratched, which greatly reduces the grinding accuracy of the grinding tool [11][12][13].…”

Ordinary diamond presents the disadvantages of poor self-sharpening and concentrated grinding stress when it is used as an abrasive. Moreover, this kind of diamond cannot be well wetted by the vitri ed bond, resulting in a lower holding force of the binder to the abrasives (i.e., the diamond is easy to detach from the binder matrix during grinding). These comprehensive factors not only reduce the surface quality of the processed workpiece, but also hinder the processing e ciency. In order to solve these problems, a new type of porous diamond with high self-sharpening properties was prepared using a thermochemical corrosion method in this study. Our results showed a great improvement in pore volume and speci c surface area of the porous diamond compared with ordinary diamond abrasive particles, and the holding force and wettability of vitri ed bond to the porous diamond abrasive particles were also improved.Compared with ordinary diamond abrasive tools, porous diamond abrasive tools showed a 29.6% increase in grinding e ciency, a 15.5% decreased in grinding ratio, a 27.5% reduction in workpiece surface roughness, and the scratches on the silicon wafer surface were reduced and re ned.
