| Abstract | Corrosion of 90Cu-10Ni alloy is related to oxide film formed in seawater. We characterize the initial oxides formed on different grains immersed in alkaline NaCl solution and reveal grain-orientation dependent Cu2O formation rate of (001) < (101) < (111) which causes Volta potential reversal among grains. We also implement the first-principles calculation on (001), (101) and (111) surfaces with monoatomic steps and demonstrate that anisotropic Cl adsorbing capacity and Cu dissolving capacity are responsible for different oxidation rates. Our results provide insights to optimize corrosion properties of conventional alloys on the concept of homogenizing oxide film by tailoring surface texture. |
