摘　　要：等离子体旋转电极制备的合金粉末具有空心粉末少、化学纯度高、球形度高、尺寸分布窄等优点,但细粉的低生产率限制了其发展。为了深入分析等离子体旋转电极雾化的制粉过程,改善制粉工艺并提高细粉生产率,综述了等离子旋转电极雾化机理、数值模拟及工艺参数对粉末影响的研究进展,指出粉末通常表现为液线破碎模式与直接液滴形成模式,提升转速与增加电流强度可提高细粉生产率,而等离子旋转电极雾化制粉过程的数值模拟还有待进一步研究。Alloy powders prepared by plasma rotating electrodes process have the advantages of less hollow powder,high chemical purity,high sphericity,and narrow size distribution,etc.However,the low yield of fine powder particles limites its development.In order to further analyze the pulverization process of plasma rotating electrode atomization,improve the pulverization process,and increase the productivity of fine powder,the study summarizes the research progress of the mechanism of plasma rotating electrode atomization,numerical simulation and the influence of technological parameters on powder;and points out that powder usually shows the mode of liquid line breaking and direct droplet formation.The productivity of fine powder can be improved by increasing the rotational speed and current intensity,but the numerical simulation of atomization process of plasma rotating electrode needs further study.
