Effect of Molybdenum on the Corrosion The corrosion behavior of high entropy alloys HEAs CoCrFeNi 2 and CoCrFeNi 2 Mo was investigated in wt percent sodium chloride NaCl at 25°C by electrochemical methods Their corrosion parameters were compared to those of HASTELLOY C 276 UNS N10276 and stainless steel 316L UNS 31600 to assess the suitability of HEAs for potential industrial applications in NaCl
