Evaluation of corrosion resistance of the single-phase light refractory high entropy alloy TiCrVNb0.5Al0.5 in chloride environment
A low density refractory high entropy alloy of composition TiCrVNb0.5Al0.5 was prepared by vacuum arc melting. Due to the formation of a single-phase BCC structure with uniform element distribution and a gradient passive film with a high concentration of passivating elements, the TiCrVNb0.5Al0.5 high entropy alloy (HEA) exhibits low corrosion current density (10(-7) similar to 10(-8) A cm(-2)), high breakdown potential (1.8-1.9 V-SCE) and excellent repassivation ability in 3.5 wt% NaCl and 1M HCl solutions. The properties were compared with HEAs, bulk metallic glasses (BMGs) and traditional alloys reported in literatures. The results show that TiCrVNb0.5Al0.5 possesses the most outstanding corrosion resistance in chloride environment. (C) 2020 Elsevier B.V. All rights reserved.
