Clinical applications require porous biomaterials; however, high porosity and hydroxyapatite contents deteriorate the mechanical properties. Hence, a functional-structural composite consisting of a central compact Ti-13Nb-13Zr core with an outer porous Ti-10%HA layer was fabricated by spark plasma sintering. The central alloy provides excellent mechanical properties (compressive strength of 1289.7MPa), while the outer layer has appropriate pore characteristics (micro and macro-pores between 100–400μm) and elasticity modulus (14.9GPa). In vitro bioactivity study showed the formation of bone-like apatite precipitates on porous Ti-HA layer. This work might provide a strategy for designing and fabricating multifunctional materials that could be potential as bone implants.
