摘　　要：为得到可用于增材制造的分散性好、粒度均匀的Cr_(2)O_(3)粉体,使用行星式球磨机对Cr_(2)O_(3)粉进行研磨,对球料质量比(1∶1.5、1∶1.3、1∶1.1、1.1∶1、1.3∶1和1.5∶1)和不同球(直径分别为6和10 mm)质量比(1∶2、1∶1、2∶1、3∶1、4∶1和5∶1)两因素进行研究。结果表明,当球料质量比为1.3∶1时,粉体的d_(10)=0.694μm,d_(50)=2.042μm,d_(90)=4.569μm,Cr_(2)O_(3)粒度最小;当不同球质量比为5∶1时,粉体的d_(10)=0.550μm,d_(50)=1.843μm,d_(90)=4.516μm,为最优粒度。To obtain Cr_(2)O_(3) powder for additive manufacturing with good dispersion and uniform particle size,Cr_(2)O_(3) powder was ground by a planetary ball mill.The influence of ball to powder mass ratio(1∶1.5,1∶1.3,1∶1.1,1.1∶1,1.3∶1 and 1.5∶1)and the different balls mass ratio(6 and 10 mm in diameter,1∶2,1∶1,2∶1,3∶1,4∶1 and 5∶1)on the grinding effect were studied.The results show that when the ball to powder mass ratio is 1.3∶1,the Cr_(2)O_(3) powder has the particle size of d_(10)=0.694μm,d_(50)=2.042μm,and d_(90)=4.569μm,which is the smallest;and when the different balls mass ratio is 5∶1,the Cr_(2)O_(3) powder has the particle size of d_(10)=0.550μm,d_(50)=1.843μm,and d_(90)=4.516μm,which is the optimal.
