Abstract

Metallic biomaterials are widely used as pins, plates, screws, needles and implants (dental, orthopedic and cardiovascular), examples being the precious metals (gold and silver), stainless steels, Co-Cr alloys and titanium alloys. The purpose of this project is to prepare and characterize new binary alloys based on zirconium and titanium, non-cytotoxic elements, aiming biomedical applications, with intermediate values to already developed in the literature, in order to understand this system, with a view to the future development of alloys with modulus of elasticity closer to the cortical bone, avoiding the bone resorption. The alloys will be designed using Molecular Orbital theory and will be obtained by acr-melting. Chemical, structural, microstructural and mechanical characterization will be made with the purpose of better understanding the relationship of the alloy microstructure and its properties. (AU)
