| Abstract Scope |
Ti-Zr-Nb-Sn alloys have been considered as promising biomedical metallic materials due to non-toxicity of Ni-free, good shape memory effect and superelasticity. Alloy fibers were prepared by melt overflow technique. The fibers were uniformly put into the predetermined packing chamber of the mold pressing equipment and the pressure was applied by screwing the bolts. The porous scaffolds with 75% porosity were produced by a solid state sintering at 1300oC and for 1 hour under the high vacuum. The porous specimen has a wide range of porosity, a large pore size, and three-dimensional network structures and then open pores of biomaterials can enhance bone in-growth, and thus improve fixation at the interface between bones and implants. The critical aim of this research is to determine the most appropriate Ti-Nb-Mo composition and to develop porous β-type Ti-Nb-Mo alloy with controlled architecture for cell renewal with emphasis on strength for biomedical applications. |
