研究了一种新型的超塑性无模拉拔技术，即局部加热和拉伸变形相结合的方法，用于制备氧化锆陶瓷管。本研究采用外径6 mm、内径4 mm的3Y-TZP氧化锆管作为超塑性材料进行实验研究。研制了一种周向均匀加热、乙炔燃烧器高温1700℃的超塑性无模拉拔装置。进行了超塑性无模拉伸实验，研究了拉深速度与进给速度之比对拉深后直径柔性可控性的影响。因此，可以通过拉拔速度与进给速度的比值来控制拉深后的面积缩小。此外，在此过程中最大可实现面积减少79.2%。从而验证了所研制的氧化锆管超塑性无模拉拔装置的有效性。
A novel superplastic dieless drawing technique with local heating and tensile deformation has been focused on for fabrication of zirconia ceramic tube. In this study, 3Y-TZP zirconia ceramic tube with outer diameter of 6mm and inner diameter of 4mm as a superplastic material is used experimentally. An apparatus of superplastic dieless drawing with rotary stage for circumferential uniform heating and acetylene burner for high temperature of 1700°C is developed. The superplastiac dieless drawing experiment is carried out to investigate the effect of the ratio of drawing speed to feeding speed on the flexible controllability of diameter after drawing process. As a result, the reduction in area after drawing process can be controlled by the ratio of drawing speed to feeding speed. In addition, a maximum reduction in area of 79.2% can be realized in this process. Consequently, the validity of developed apparatus of superplastic dieless drawing for Zirconia ceramic tube can be demonstrated.
