Surface characteristics in the ultrasonic ductile honing of ZrO2 ceramics using coarse grits
Experimental research into the surface characteristics in the ultrasonic ductile-regime honing of ZrO2 engineering ceramics with a new-type ultrasonic honing machine was carried out. When the results are compared with those for common honing five characteristics are clear: (1) with the same cutting depth, the grooves scored in ultrasonic grinding are shallower; (2) the width at the bottom of the grooves is greater than that of common honing and close to the amplitude of the ultrasonic wave; (3) fracture and pits on the ultrasonically honed surface are shallower and peel off as layers, while those on the common honed surface exhibit chap abscission; (4) on the ultrasonically honed surface fracture mostly occurs on the boundary of the grooves and in even wide grooves fracture is much less extensive, whilst on the other hand, in common honing, at the bottom of the grooves a greater number of

表面特征的韧性超声珩磨ZrO2陶瓷磨料粗实验研究表面特征 超声波延性域珩磨ZrO2陶瓷工程与新型超声波珩磨机进行了研究. 当结果相比,通用珩磨五个特征是很明确的: ( 1 )用同样的切削深度,沟槽得分超声波磨削的深度较浅; ( 2 )宽度在底部的沟槽,比普通珩磨和密切的 超声波幅值; ( 3 )骨折和坑穴超声珩磨表面的浅薄和剥下来作为层 而那些在普通珩磨表面证物章脱落; ( 4 )在超声珩磨表面裂缝多发生在边界上的沟槽,甚至在宽槽 骨折是少得多广泛,而在另一方面,在普通珩磨, 在底部的沟槽较多骨折的观察,以及对边界; ( 5 )对地面锆,因为这两种方法,小家伙开裂看得见, 不像一个工件的氮化硅. 根据开裂共同珩磨是较超声波珩磨. 在边缘的损伤面积为超声珩磨广泛裂纹因特殊跨结晶破裂被发现.
