| 摘 要： | 在球径、转速和球料比相同的情况下,分别采用溶剂汽油和甲苯作为滚动球磨的液体介质,对Sm(Co,Fe,Cu,Zr)7.4合金粉进行了一系列的试验.测定了2种介质环境下,试样的粒度及氧含量与球磨时间的关系.结果发现,采用溶剂汽油作为液体介质时,较强的静电排斥力有利于球磨过程中粉末颗粒的分散,促进粉末的细化.

| Abstract: | A series of ball milling test for Sm(Co, Fe, Cu, Zr)_(7.4) alloyed powder was conducted under the same conditions such as ball radius, rotating speed and ball material ratio expect for the mill liquid. The granularity and oxygen content of the powder obtained under gasoline and toluene were measured. The results show that the former can increase the rate of particle-size reduction due to its better electrostatic repulsion. |
