dc.description.abstractPorous titanium alloys are presently well-considered materials for orthopedic applications owing to their superior mechanical properties, excellent biocompatibility and high resistance to corrosion. Also, porous alloys are potentially minimizing the risk of stress-shielding effect as compared to bulk implant materials. In this present work focused to examine electrochemical corrosion behavior of porous Ti-20Nb-5Ag alloy (wt%) with different porosity levels. This designed alloy composition of elemental powders was mixed through mechanically alloying. The mechanically alloyed powder blended with four different amounts of NH4HCO3 (wt%), use to prepare the porous Ti-20Nb-5Ag alloy with porosity ranging from 22% to 68%. After the successful development of porous samples, we investigated the effect of porosity levels on electrochemical corrosion behavior of porous Ti-20Nb-5Ag alloys by means of potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) in simulated body fluid (SBF) at 37 °C. The results show that an increasing the trend of porosity level causes a reduction of corrosion resistance. With increasing porosity, the corrosion current density increased and decreases the electrochemical polarization resistance in the SBF solution. © 2019 Elsevier Ltd. All rights reserved.en_US
