| 摘 要： | 本文通过射频等离子方法制备了高度球形化的TC4(Ti6Al4V)合金粉末。主要探究仪器送粉喷嘴高度、产生等离子体的功率、反应室的压力、原料粉体的粒径分布、送粉速率以及载气的气流速率等对于粉体球化率的影响，通过调节上述因素形成对比实验并得到不同实验条件下的球化粉体。通过SEM图像可观察粉体的形貌变化并计算比较粉体的球化率，通过XRD图可知球化前后粉体相结构不发生变化，观察球化粉末横截面可知粉末为实心球体且表面光滑，同时可发现球化后粉末流动性明显提高，松装密度大，粒径分布窄，适合3D打印等应用技术对于合金粉体的要求。实验中，调节送粉喷嘴高度为12.5cm，反应室压力为14.7psia，送粉速率为1.742g／min，产生等离子气的功率为27.2kW且控制原料粉体的平均粒径在38～63微米时可使得球化率达到99%，明显高于其他球化粉末制备方法。
