摘要
采用球磨法制备钉扎型氧化铝/铝金属陶瓷复合粉体,为制备高性能金属陶瓷材料提供原料基础。研究表明:随着球磨时间的增加,Al2O3颗粒在Al球表面的钉扎数量呈先增多后减少的趋势,球磨转速对Al2O3在Al球表面的钉扎数量呈先增多后减少的趋势;随着球料比的增大,Al2O3在Al球表面分布增多,综合考虑其性价比,采用球磨时间为24 h、转速为100 r/min和球料比为1∶2的工艺条件制备钉扎型氧化铝/铝金属陶瓷复合粉体较为适宜。
The Al2O3/Al cermet composite powders were prepared via the ball milling method,which provide raw materials for preparing high performance cermet materials. The results show that the number of Al2O3 particles on the surface of Al particles increases first and then decreases with increasing the ball milling time and milling rotating speed. The number of Al2O3 particles on the surface of Al particles increases with increasing ball to powder mass ratio. The analysis of the ratio of performance to price shows that the better parameters for preparing the pinned Al2O3/Al cermet composite powders are as follows:the ball milling time24 h,the ball milling rotating speed 100 r/min and the ratio of ball to powder 1∶2.
