Study on the Influence of Ball Milling Process and SiC Content on TC11 Titanium Alloy Powder

摘要: 本文采用机械球磨法，通过调整不同球磨时间、转速、SiC_p含量来实现复合粉末的优化制备，利用扫描电镜(SEM)、能谱仪(EDS)、X射线衍射(XRD)等研究了球磨速度、球磨时间及SiC含量对复合粉末的影响。结果表明：球磨转速、球磨时间及SiC含量对复合粉末的形貌、尺寸和分布情况均存在影响。球磨参数选取球料比4:1、转速200 r/min、球磨时间6 h能够实现复合粉末的优化制备。

Abstract: In this paper, the mechanical ball milling method was adopted to achieve the optimized preparation of composite powders by adjusting different ball milling times, rotational speeds, and SiC_p contents. The effects of ball milling speed, ball milling time, and SiC content on the composite powders were investigated using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and other techniques. The results show that ball milling rotational speed, ball milling time, and SiC content all have significant effects on the morphology, size, and distribution of the composite powders. The optimized preparation of composite powders can be achieved when the ball-to-powder ratio is 4:1, the rotational speed is 200 r/min, and the ball milling time is 6 h.
