摘要

高性能金属粉末是金属增材制造技术发展的重要支撑。采用高能密度激光冲击 – 离心复合雾化制粉新方法制备了锡铜合金粉末。结果表明，在试验参数下，所有金属粉末均具有良好的球形度，粒径主要分布在 1~20μm 之间，表面光滑，使用较大的能量密度有利于获得粒径分布较窄的金属粉末，并初步探讨了激光雾化粉末形成的机理。

Abstract

High–performance metal powder is an important support for the development of metal additive manufacturing technology. A new method of laser shock–centrifugal atomization was used to prepare tin–copper alloy powder. The influence of process parameters on the morphology of metal powders was studied. The results show that the metal powder particle is spherical with smooth surface

and is mainly distributed in range of 1–20μm. A higher laser energy density input is beneficial to obtain metal powders with a narrower particle size distribution.The ration mechanism of laser atomized powder is discussed preliminarily.
