摘要

采用高能球磨技术获得Cu/SiC不同配比的混合粉末

通过正交试验研究了高能球磨过程中球磨时间、球料比以及球磨机转速对粉末粒径的影响。通过EDS能谱分析了粉末的包覆效果。结果表明

球磨时间对粉末粒径的影响大于球磨机转速

球料比对粉末粒径的影响最小。其中

球磨时间越长

对粉末细化作用越明显;球磨机转速越大

粉末粒径越小;随着球料比的减小

粉末粒径呈先减小后增大的趋势。当球磨时间为20h

球料比为20∶1

转速为300r/min时

球磨出的粉末粒径最小

且球磨粉末出现明显包覆效果。

Abstract

Cu/SiC mixed powder with different mixture ratio was prepared by the high-energy ball milling technology.Effects of ball milling time

ratio of ball to material and speed of ball milling on powder particle size were analyzed by orthogonal testing.Cladding effect of powder was analyzed by EDS.The results show that effects of milling time on powder particle size are the dominant

and then rotational speed of ball milling

ratio of ball to material.With the increase of milling time

refining effect on powder becomes more obvious.With increasing in ball milling speed

the powder particle size can be refined.In addition

with the decrease of ball to material ratio

powder particle size is decreased firstly and then increased.With the ball milling time of 20 h

ratio of ball to material of 20∶1and rotational speed of300r/min

powder particle size is the smallest.And cladding effect in the ball milling powder exhibits obvious.
