文摘
- •
316L stainless steel was potentiodynamically polarized in NaCl solution.
- •
ToF SIMS depth profiles of surface film on 316L stainless steel were analysed.
- •
Cl− ions penetrated and accumulated at the metal/film interface.
- •
Cl− ion intensities increased with the potential and charge density.
- •
The results support passivity breakdown at the metal/film interface.
