摘要
以钛粉、钼粉和锰粉为原料,碳酸氢铵颗粒为造孔剂,采用粉末冶金工艺制备出医用多孔Ti-Mo-Mn合金,并研究了锰含量对多孔Ti-Mo-Mn合金微观结构和力学性能的影响.结果表明,随着锰含量从 0wt%增加到 10wt%,多孔Ti-Mo-Mn合金的孔隙率降低,大孔孔径少量减小,β-Ti相的比例相对增多,弹性模量和抗压强度相应增加.含 7.5 wt%Mo和5wt%～10wt%Mn的多孔Ti-Mo-Mn合金具有三维连通的多孔结构和良好的力学性能,有潜力用作皮质骨缺损修复材料.
Abstract
Titanium powder,molybdenum powder and manganese powder were used as raw materials.The ammonium bicarbonate particles were used as pore-forming agent,and biomedical porous Ti-Mo-Mn alloys were prepared by powder metallurgy process.The effects of Mn content on the microstructure and mechanical properties of porous Ti-Mo-Mn alloys were investigated.The results show that with the increase of Mn content from 0wt%to 10wt%,the porosity of porous Ti-Mo-Mn alloys gradually decreases,the macropore size decreases slightly,the proportion of β-Ti phase increases relatively,and the elastic modulus and compressive strength increases accordingly.Porous Ti-Mo-Mn alloys with 7.5wt%Mo and 5wt%-10wt%Mn have a three-dimensional interconnected porous structure and good mechanical properties,which have the potential to be used as cortical bone defect repair materials.
