The corrosion resistance of stainless steel comes from the passive film. Surface modifications can enhance the resistance and bring about new functions. Here in this report, a novel approach for in-situ measuring the thickness of passive film in solution was first introduced. Next, a mop electrolytic fluorine treatment was used to improve the corrosion resistance. Then, ultrasound was applied to suppress both the pitting corrosion’s initiation and growth. Finally, a rough surface was produced and then the deposition of a PFDS or PE film was used to produce hydrophobicity. The corrosion behavior of such hydrophobic surfaces was confirmed.
