作为重熔粉末的对比,对相同工艺下制备新粉末球形度进行了表征,表征方法采用SEM拍摄的粉末颗粒二维投影的面积径与周长径的比值来表征
As a comparison of remelting powder, the sphericity of new powder prepared under the same process was characterized, and the characterization method was characterized by the ratio of area diameter to perimeter diameter of powder particles in two-dimensional projection taken by SEM.
