采用高能球磨48 h制备Ti-24Nb-4Zr-7.9Sn(TNZS)、5%TiO_2/TNZS及5%HA/TNZS混合粉末(质量分数,下同)并进行冷压烧结,研究了3种混合粉末的形貌、物相及冷压烧结后3种TNZS基生物材料的组织、成分、相组成、孔隙特征及弹性模量。高能球磨48 h的3种混合粉末都发生机械合金化;烧结后TNZS相组成为α-Ti和β-Ti,5%TiO_2/TNZS相组成为α-Ti、β-Ti、金红石TiO_2和锐钛矿TiO_2,5%HA/TNZS相组成除α-Ti、β-Ti、HA外,还有Ti_2O、Ca TiO_3、CaO和TixPy新相生成;三者孔隙率分别为2.466%、5.030%和13.027%;三者弹性模量分别为64.00、103.93和119.43 GPa。
Ti-24Nb-4Zr-7.9Sn (TNZS), 5% TiO 2 / TNZS and 5% HA / TNZS mixed powders were prepared by high energy ball milling (mass fraction) The morphology, phase and microstructure, composition, phase composition, pore characteristics and elastic modulus of three kinds of TNZS-based biomaterials after cold pressing were studied. The three kinds of mixed powders of high-energy ball milling for 48 h all undergo mechanical alloying. After sintering, the composition of TNZS phase is α-Ti and β-Ti. The composition of 5% TiO 2 / TNZS is α-Ti, β-Ti, rutile TiO 2 and anatase In addition to α-Ti, β-Ti and HA, the phase composition of ore TiO_2 and 5% HA / TNZS is also formed by new phase of Ti_2O, Ca TiO_3, CaO and TixPy.The porosity of the three are 2.466%, 5.030% and 13.027% ; The elastic modulus of the three were 64.00,103.93 and 119.43 GPa.
