摘　　要：通过粗磨粒金刚石油石普通和超声珩磨ZrO2 工程陶瓷的表面特征试验 ,分析了所产生不同结果的原因 ,给出了普通和超声珩磨速度对表面破碎率的影响。研究表明 :随着珩磨速度的提高 ,珩磨表面的破损率逐渐减小。对普通珩磨 ,在所给速度范围内 ,整个表面的破碎点面积总和均大于被观察表面的 30 % ,最大的达到70 %。而超声珩磨均可获得延性切削表面 ,破碎率均不大于 10 % 。s:By experiment of common honing and ultrasonic honing on ZrO 2 engineering ceramics, in this paper, we analyze the different ground surfaces and bring forward the influence rule of ultrasonic honing speed on breaking rate of the machined surface. Through the experiments, it is concluded that the breaking rate of honing surface decreases as honing speed rised at the range of given speed. In common honing, the total breaking area of the whole surface was greater than 30% (sometimes it increased up to 70%) of the observed surface. While in ultrasonic honing, the breaking rate was less than 10% and the ductile trail scored by grinding grains was very clear because the cutting surface obtained at the experiment speed was in ductile area.
