Abstract

The tribo-corrosion performance of 7075-T6 Al-alloy in 3.5% (mass fraction) NaCl solution was studied, while the variation of the passivation film and the tribo-corroded surface was also examined versus the tribo-corrosion process. The results demonstrate that sliding friction leads to a decrease in the open-circuit potential (OCP) and the potentiodynamic polarization corrosion potential of Al-alloy, whereas, a significant increase in the corrosion current density. In constant cathodic potential condition, the passivation film was removed due to the friction, accelerating the hydrogen evolution reaction. In constant anodic potential condition, friction leads to a significant increase in corrosion current density, accelerating the corrosion of the alloy. XPS analysis result indicates that the primary constituent of the passivation film is Al₂O₃. In conditions of dry sliding friction, OCP, constant anodic potential, and constant cathodic potential, respectively, the values of friction coefficient and wear rate can be ranked as the following decline order: dry sliding friction>constant anodic potential> OCP>constant cathodic potential. The wear mechanism in dry sliding friction condition is adhesive wear, the wear mechanisms in OCP and constant cathodic potential conditions are abrasive wear, and the wear mechanism in constant anodic potential condition is corrosive wear.

Key words: 7075-T6 Al-alloy corrosion tribo-corrosion wear mechanism
