摘要：

The effect of Mo addition on corrosion behavior of (CoNiV)100_xMox medium entropy alloys (MEAs) in 0.5 M H2SO4 solution was investigated. Results revealed that the introduction of Mo element by micro alloying can significantly improve the corrosion resistance of CoNiV MEA, despite the precipitation of the second phase. Besides, the competition effect between microgalvanic coupling and micro alloying in dominating the corrosion resistance of (CoNiV)100_xMox MEAs was discussed in detail.
