| 摘 要： | 采用改进的凝胶注模技术制备多孔陶瓷结合剂超细金刚石砂轮，研究6种不同质量分数磨料(质量分数分别为27%、30%、33%、36%、39%、42%)的多孔金刚石砂轮的显微结构和磨削性能。结果表明:磨料的质量分数直接影响砂轮磨削时的磨削电流、砂轮磨损速率，进而影响硅片磨削后的表面一致性。使用磨料质量分数为39%的砂轮时，硅片磨削后可获得粗糙度为4.8 nm的光滑表面。

| Abstract: | The porous vitrified-bond ultrafine diamond grinding wheel was fabricated through a modified gel casting technique in this study. Meanwhile, the microstructure and grinding performance of porous vitrified-bond ultrafine diamond grinding wheels, were evaluated at six different abrasive fractions (27%, 30%, 33%, 36%, 39%, 42% in mass percentage, respectively). The abrasive fraction was found to play an important influence directly on the grinding current, wheel wear rate and hence affected the surface integrity of Si wafers. Results revealed that a smooth surface with roughness of 4.8 nm was achieved by using the grinding wheel with abrasive fraction of 39%. |
