Abstract:

Titanium and its alloys have been widely utilized in the bio-medical applications for decades due to their good mechanical properties, corrosion resistance, osseointegration and bio-compatibility. Although the elastic moduli of these materials are lower than those of other bio-medical metals, human bone degradation still occurs owing to the difference of the elastic moduli between human bone and titanium. Space holder technique is one of the effective ways to reduce elastic modulus. Our study aims to produce human bone mimetic titanium structures with excellent mechanical properties (low elastic modulus and high compressive yield strength) using space holder technique and spark plasma sintering process. In this study, porous titanium structures consisting of two different inner and outer porosities were made and their compressive strength and elastic modulus were evaluated. Special attention was focused on the soundness of interface during the deformation.
