| Abstract | The mechanisms of hydrostatic pressure promoting the electrochemical corrosion of pure iron in 3.5% NaCl solution were studied using electrochemical measurements and molecular dynamics simulation at different hydrostatic pressures. The main results show that hydrostatic pressure amplifies psi(1) effect by changing the Fe2+ profile at the metal/solution interface and decreasing the Helmholtz layer's thickness. It is the determinant of the enhancement of the iron dissolution rate at hydrostatic pressure. On the contrary, the adsorption of Cl- at the iron surface does not play an important role in the promoted corrosion process by hydrostatic pressure. (C) 2020 Acta Materialia Inc.
