Resumo: The development of new design approaches for biomedical applications using conventional and well accepted bio inert materials is an actual challenge. This study proposes a bilayered materials design approach obtained by hot pressing and is concerned with the influence of sintering pressure on the interface reaction between titaniumalloy (Ti6Al4V) and zirconia (ZrO2), on density and mechanical properties of the Ti6Al4V-ZrO2. For this purpose, different sintering pressureswere studied (P=5, 20 and 100MPa). Bilayered materialswere produced by hot pressing process, at T=1175 °C. Microstructural characterization showed that Ti6Al4V reacts with ZrO2 (for Pâ ¥20 MPa) and that the interface reaction is strongly dependent on pressure. Additionally, an oxygen-deficient ZrO2 â x black zirconia layer was obtained for specimens produced at P=20 and 100MPa as result of decreased O/Zr ratio due to Ti diffusion into ZrO2 side. Young's modulus and hardness properties were evaluated by nanoindentation test. The results showed that these properties are influenced by sintering pressure, increasing with an increase on sintering pressure, with the highest improvement for specimens produced at higher pressure.
