Abstract

© The Electrochemical Society. The present work is a study of the thermally treated [Ti] alloy Ti6A14V by annealing at two different temperatures [700 and 800 °C] and its resistance and corrosion behavior were evaluated using electrochemical techniques such as: polarization curves [CP] and electrochemical impedance spectroscopy [EIS] in a Hank's salt solution. In addition, the samples were characterized by scanning Electron Microscopy [SEM] and microanalysis by X-ray Spectroscopy by energy dispersion [EDS], in their conditions of arrival [untreated] and after thermal treatments [TT] and chemical conversion with cerium and lanthanum salts [CCT]. The results of the electrochemical tests indicate the decrease in the corrosion rate of the samples with CCT and TT with respect to the untreated and the presence of biphasic microstructure constituted by an α - rich [Alrich] matrix with β [V - rich].
