The relationships among equivalent elastic modulus of porous titanium alloy / HA coating composite were investigated by using finite element method in this paper. The method of porosity and pore shape of bio-derived bone scaffold materials was ascertained by the elastic modulus of natural bone. The equivalent elastic modulus of porous titanium alloy / HA coating composite decreased with increasing porosity, decreased with the increase of fractal dimension of porosity space, and increased with the increase of fractal dimension of solid matrix. If the porosity ranged from 40% to 50% and pore/solid fractal dimension ranged from 2.77 to 2.96, the equivalent elastic modulus of porous titanium alloy / HA coating composite was consistent with the elastic modulus of natural bone when the bio-derived bone scaffold materials were fabricated by porous titanium alloy / HA composite coating materials.
