| 摘 要： | 采用高能机械球磨和脉冲电流活化烧结方法制备了一种新型的β-钛合金基体的Ti35Nb2.5Sn/10HA生物复合材料。研究了机械球磨不同时间的Ti35Nb2.5Sn10HA粉体以及烧结样品的微观组织。结果表明:经机械球磨8h后,粉体中的α-钛开始向β-钛转化。当球磨时间达到12h时,球磨粉体中的α-钛相完全转化为β-钛相,而且得到超细尺寸的复合粉体。用球磨12h的粉末烧结制备的复合材料具有超细晶粒结构,烧结得到的复合材料的硬度和相对密度都随着球磨时间的延长而增加。

| Abstract: | A new β-Ti based Ti35Nb2.5Sn/10 hydroxyapitite(HA) biocompatible composite was fabricated by mechanical milling and pulsed current activated sintering(PCAS).The microstructures of Ti35Nb2.5Sn/10HA powder particles and composites sintered from the milled powders were studied.Results indicated that α-Ti phase began to transform into β-Ti phase after the powders were mechanically milled for 8 h.After mechanical milling for 12 h,α-Ti completely transformed into β-Ti phase,and the ultra fine Ti35Nb2.5Sn/10HA composite powders were obtained.And ultra fine grain sized Ti35Nb2.5Sn/10HA sintered composites were obtained by PCAS.The hardness and relative density of the sintered composites both increased with increasing the ball milling time. |
