The electrochemical properties of the samples were examined using electrochemical techniques: such as open-circuit potential, potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS), in two electrochemical media of artificial saliva and fluoridated artificial saliva (0.1% fluoride ions, F ) at 37 °C. Fluoride is commonly included in toothpastes, odontological gels and dental rinses to prevent dental caries and relieve dental sensitivity. The passive behaviour for all the titanium samples is observed for both solutions. The Ti60Ta alloy appears to possess superior corrosion resistance than the Ti12Mo and Cp-Ti in both electrochemical media.

From the aluminium bronzes can be made bars, profiles, strips, bearings, gears, valves, coins, electrical conductors. After the preparation, melting and homogenization of the alloy in high-frequency induction furnace, the alloy was cast in a metal mold. Experimental tests were subjected to measurements of chemical composition, microstructure and hardness.
