摘要: 本文研究了离心雾化工艺参数对LY12硬铝粉末特性的影响。结果表明,随着起绐雾化温度的增加,粉末平均尺寸先降后升,细粉率则反之;当雾分盘直径减小到一定值时,粉末平均尺寸和细粉率增加。粉末呈泪滴状和少量球状。

Abstract: The characteristic of LY12 alloy powders made by centrifugal atomization were studied. The results show that as the initial atomizing temperature elevated, the average size of the powders decreased firstly, then increased, and the percentage of the fine powders changed in the others direction. When the diameters of the atomizing disc decreased in certain range, the average size of the powders and the percentage of the fine powders increased .The powders were tear-drop of spherical shaped.
