Abstract

Currently, the removable and/or fixed prosthesis are usually realised from Co-Cr-Mo alloys, which possess good corrosion resistance owing to the appropriate microstructure, but presents low machinability. Knowing that titanium is one of the best biocompatible metals, widely used as implant, due to its high biocombatibility, bioinert capacity and low density, the paper presents the results concerning structure and surface properties of new CoCrMoTi alloys. There were elaborated three composition of cobalt alloys, with 1%, 3% , respectively 5% Ti. The main structural features were put in evidence, by metallographic analysis, scaning electron analysis and X-Rays diffraction. Finally, the isometric aspects by atomic force microscopy (AFM) were shown, revealing the level of roughness in milled and polished state..
