The influence of chromium and molybdenum on the repassivation of nickel‐chromium‐molybdenum alloys in saline solutions

The electrochemical properties and compositions of passive, transpassive, and re‐formed passive oxides on the Ni‐Cr‐Mo alloys C22 (high Cr/low Mo) and HYBRID BC1 (low Cr/high Mo) have been studied in 5.0M NaCl solutions. At low potentials in the passive region, the oxide was less resistive on BC1 compared to C22, possibly due to the influence of Mo in increasing the number of defects in the oxide. At higher potentials in the passive region, both...
