Taking dodecanethiol as the representative, we investigated the corrosion inhibition performance of SAL in seawater under pressures from 0.1 to 9 MPa. By using scanning Kelvin probe, the dodecanethiol SAL is confirmed to build on Cu surface, and the modification of SAL has positively shifted the surface potential to realize the inertness. Electrochemical techniques, such as electrochemical impedance spectroscopy and potentiodynamic polarization were used to reveal the corrosion behavior of Cu modified by SAL under the different pressure, i e, 0.1, 3, 6, and 9 MPa. It is indicated that the longer modification time affords better corrosion resistance to Cu. Higher static pressure is easier to deteriorate the corrosion inhibition capability due to the penetration effect. A plausible mechanism is proposed to illustrate the degradation process of SAL in the high pressure seawater environment.
