- Stabilizes the passive film: In chloride‐bearing solutions, the thin chromium‐rich oxide film on stainless steel can break down locally, initiating pits. Molybdenum enriches the passive layer with Mo-oxides (e.g., MoO₃) which are chemically stable and hinder Cl⁻ penetration into the film.
- Enhances repassivation kinetics: Even if a pit starts, Mo-containing steels can “heal” the damaged area more rapidly by reforming a protective oxide, raising the repassivation potential relative to Mo-free steels.
- Raises pitting potential: Electrochemical tests show that adding Mo shifts the pitting potential to more positive values, meaning a higher chloride concentration or more aggressive conditions are required before pits initiate.
