Abstract:

This works presents the fabrication of a two-layer material composed of a porous Ta core and a dense Ti6Al4V (Ti64) shell by pressing and sintering. It is part of a research project that aims at fabricating multimaterial bone implants that will allow a faster osseointegration. The sintering behavior of two-layer samples is studied by dilatometry. The interface bonding between the Ti64 and Ta layers is analyzed by SEM. Two layers are clearly obtained with a bonding developed by the solid state diffusion of Ta particles into Ti64 during sintering. The mechanical properties of the component are mainly dominated by the porous layer showing a wide pore size distribution, which should contribute to improve the cell and bone growth. The density of such materials is much lower than the one of pure Ta. It is concluded that hybrid materials can improve the response to osseointegration.
