| 摘 要： | 进行了Ti6A14V合金锆刚玉页轮和碳化硅页轮的磨削性能试验研究，分析了磨削用量对磨削力、磨削温度和磨削表面完整性的影响。磨削力通过KISTLER9265B测力仪测定，磨削表面温度由NIUSB-621X信号采集系统测得，磨削表面形貌和金相组织由HiroxKH-7700型体视显微仪和Quanta200型扫描电镜（SEM）观察，表面粗糙度由Mahr Perthometer M1粗糙度仪测得，表层显微硬度通过HVS—1000硬度计测定。研究结果表明：页轮磨削钛合金工件表面没有发生烧伤现象，磨削热影响区厚度小于50μm，锆刚玉页轮比碳化硅页轮更适合干式磨削钛合金。

| Abstract: | The grindability of alloy Ti6Al4V with zirconia alumina and silicon carbide flap wheels, and the effect of process parameters on grinding forces, grinding temperature and surface integrity are studied. The grinding forces are measured by KISTLER 9265B dynamometer. The grinding temperature response is obtained by NI USB-621X signal collection system. Ground surface morphology and the metallographic structure are observed by the Hirox KN-7700 stereoscopic microcope and the Quanta200 scanning electron microscope (SEM). Surface roughnesses are measured by Mahr Perthometer M1 instrument. The surface microhardnesses are detected by HXS-1000 microhardness tester. |
