| The mechanical properties of materials used for orthopaedic implants are of major importance for the bone remodeling processes and for the bio-functionality. Young's modulus for metallic biomaterials is higher than for cortical bone (7-35 GPa): stainless steels - higher than 208 GPa, titanium and usual titanium alloys - higher than 102 GPa, Co-Cr alloys - above 201 GPa. As a result, the mechanical mismatch implant - tissue generates bone atrophy due to the ``stress shielding'' effect. The paper contains elaboration and characterization of a new two Ti-based alloys for medical applications. Samples were cuted and tested to obtain the main mechanical properties (hardness, indentation etc.), after that were measured the cell viability on new Ti alloys. The results obtained promise new alloys with improved properties compared to the classical alloys. |
