Appropriate increase in Mo/Nb content leads to increased Laves phase and enhances corrosion resistance
Excessive Mo/Nb causes more severe microgalvanic corrosion between FCC and Laves phases, decreasing corrosion resistance
Laves phase is more resistant to attack by corrosive species
Presence of Mo, Nb, and Cr facilitates adsorption of H₂O/O on alloy surface, promoting protective passive film formation
