Abstract
Monel 400 alloy is widely used in marine engineering due to its corrosion resistance. In this study, the tribocorrosion behavior of Monel 400 alloy has been investigated under cathodic and anodic polarization conditions. The results revealed that the material loss increased under both cathodic and anodic polarization, while the damage mechanism varied. Under cathodic polarization condition, the damage is caused by delamination of the worn surface and crack propagation in the subsurface, which gets more seriously at more negative polarization values. Under higher anodic polarization values, the lubricating performance of in -situ generated corrosion product was weakened. As the anodic polarization value increased, the diameter of corrosion products increased and got easier to be sheared-off during the sliding process.
