Tribocorrosion of Passive Materials: A Review on Test Procedures and Standards

(a) Polarization curves of a Monel K500 alloy in artificial seawater obtained in corrosion-only and tribocorrosion conditions. (b) Polarization curve of Monel K500 alloy in artificial seawater and evolution of coefficient of friction obtained during measuring. The corrosion potential under tribocorrosion conditions is shifted to more cathodic potentials, and the corrosion current density increases by two orders of magnitude. The coefficient of friction decreases with higher anodic potentials as a consequence of the presence of oxide film on the surface [29].
