摘　　要： 采用不同球磨介质对Ti+30％HA(质量分数)原始粉料进行高能球磨,研究了球磨工艺对 Ti／HA复合材料原始粉料细化过程的影响。研究结果表明:采用干磨工艺时,随着球磨时间的延 长,HA粉得到明显的细化,而Ti粉细化不明显,HA粉堆积覆盖在Ti粉大颗粒上;采用湿磨工艺 时,HA粉和Ti粉都明显细化,表明湿磨工艺可以提高球磨的细化效果,提高HA粉在Ti粉中的 均匀弥散分布程度。 Ti+30% HA(mass fraction) powder was processed by high-energy ball milling in different milling media. The effects of milling technology on refinement of Ti/HA composite were studied. The results show that during dry-milling, increasing milling time can greatly refine HA powder, but has almost no influence on the refinement of Ti powder. Under this condition, large Ti powders are packed and wrapped by fine HA powders. During wet-milling, both Ti powder and HA powder can be obviously refined by increasing milling time, and two kinds of powders are mixed together. Therefore, the existence of wet-milling medium can increase the effect of milling and dispersive distribution of HA in Ti powder.
