Resumo: The objective of the present study was to evaluate the corrosion resistance of the experimental alloy Ti-35Nb-7Zr-5Ta, modified by laser beam, in a physiological solution of 0.9% NaCl. This evaluation was carried out by open circuit potential analysis (EOCP), potentiodynamic polarization curves and cyclic polarization curves. The open circuit potential curves show the specimen irradiated by laser beam at 35 Hz presented a more stable and corrosion resistant surface. It was observed in the polarization curves, low current densities in the order of nA /cm2, for all specimen indicating an expected passive behavior for the investigated alloy. The cyclic polarization curves show that for specimen treated with laser, the potential for repassivation (Er) is greater in relation to the potential for corrosion (Ecorr), which indicates greater resistance to corrosion of metal alloys when treated with laser.

Ti-35Nb-7Zr-5Ta, modificado por rayo láser, en una solución fisiológica de NaCl al 0,9%. Esta evaluación se llevó a cabo mediante análisis de potencial de circuito abierto (EOCP), curvas de polarización potenciodinámica y curvas de polarización cíclica. Las curvas de potencial de circuito abierto muestran que la muestra irradiada por rayo láser a 35 Hz presentó una superficie más estable y resistente a la corrosión. Se observó en las curvas de polarización, densidades de corriente bajas del orden de nA / cm2, para todas las muestras indicando un comportamiento pasivo esperado para la aleación investigada. Las curvas de polarización cíclica muestran que para las muestras tratadas con láser, el potencial de repasivación (Er) es mayor en relación al potencial de corrosión (Ecorr), lo que indica una mayor resistencia a la corrosión de las aleaciones metálicas cuando se tratan con láser.O objetivo do presente estudo foi avaliar a resistência à corrosão da liga experimental Ti-35Nb-7Zr-5Ta, modificada por feixe de laser, em uma solução fisiológica de NaCl a 0,9%. Esta avaliação foi realizada por análise de potencial de circuito aberto (EOCP), curvas de polarização potenciodinâmica e curvas de polarização cíclica. As curvas de potencial de circuito aberto mostram que a amostra irradiada por feixe de laser a 35 Hz apresentou uma superfície mais estável e resistente a corrosão.
