摘要

摘要: 以Ti6Al4V ELI（TC4 ELI）钛合金棒料为原料，采用等离子旋转电极雾化法制备TC4 ELI球形粉末，研究了电流和电极转速对粉末粒度分布及粉末特性的影响，利用扫描电镜（SEM）对粉体形貌进行了观察。结果表明：电流保持600 A不变时，随着电极转速提高，53～106 µm TC4 ELI粉末收得率增大；当电极转速为44000 r/min时，随着电流的增大，粒径<106 µm的粉末收得率略有增加，所得粉末松装密度在2.59～2.72 g/cm³范围内，振实密度为3.0 g/cm³，氧含量（质量分数）在560×10^－6～750 ×10^－6，流动性（50 g计）为30.6～35.7 s；粉末成球率高、球形度好，边缘光滑无杂质，球形度>90%。

Abstract: Using titanium alloy rod TC4 ELI as raw material, spherical TC4 ELI powder was prepared by plasma rotating electrode method (PREP). The effects of current and electrode speed on the particle size distribution and powder properties were investigated. The morphology of the powder was observed using a scanning electron microscope (SEM). The research results show that when the current remained constant at 600 A, the yield of 53~106 µm TC4 ELI powder increases with the increase of electrode speed. At an electrode speed of 44000 r/min, the yield of powder with a particle size of less than 106 μm increases slightly with increasing current. The obtained powder has a loose packing density in the range of 2.59~2.72 g/cm³, a compacted density of 3.0 g/cm³, an oxygen content in the range of 560×10^－6~750×10^－6and a fluidity(calculated as 50 g) of 30.6~35.7 s. The powder has high sphericity rate, good sphericity, smooth edges without impurities and a sphericity greater than 90%.
