Ti-15Mo/HA生物医用复合材料在模拟体液环境下的摩擦学行为
Tribological behavior of Ti-15Mo/HA composite in simulated body fluid environment for biomedical applications
摘要
Abstract
Ti-15Mo/HA composite is prepared by powder metallurgy,and the influence of hydroxyapatite(HA)on the microstructure,microhardness,and tribological behavior is studied.The results show that the Ti-15Mo/HA composite consists of increased α-Ti,decreased β-Ti and a variety of ceramic phases(CaTiO3,Ca3(PO4)2,CaO,etc.)with the increase of HA content.The hard ceramic phase generated after the addition of HA increases the microhardness of Ti-15Mo/HA composite.The friction coefficient and wear rate of Ti-15Mo/HA composite is apparently low under simulated body fluid environment due to the solid solution strengthening of Mo in Ti,the dispersion strengthening of ceramic phase,and the lubrication of liquid.Ti-15Mo/5HA displays more excellent wear resistance than the other composite with an average friction coefficient of 0.42 and a wear rate of approximately 2.51×10-4 mm3/(N·m).Ti-15Mo alloy is a combination of adhesive wear and abrasive wear.Ti-15Mo/HA composite is mainly subjected to abrasive wear,together with adhesive wear.The Ti-15Mo/5HA composite prepared by powder metallurgy shows good wear resistance and has potential application in the field of hard tissue replacement and repair materials.关键词
