Abstract
This study investigates the corrosion wear behavior of 30CrNi2MoVA steel in a simulated seawater environment using an electrochemical workstation and a friction-wear testing machine. The results indicate that under dry friction conditions, an increase in load leads to an increase in friction coefficient and wear depth. In seawater, an increase in speed results in a decrease in friction coefficient and an increase in wear depth, while the effect of load on material loss is minimal, highlighting the crucial role of speed in corrosion-wear behavior. The synergistic effect of corrosion and wear causes more severe damage than dry friction. The corrosion wear behavior of 30CrNi2MoVA steel is a dynamic process of “mechanical deoxidation-chemical reoxidation,” as evidenced by the change in corrosion potential from −0.6502 V to −0.8646 V and increased material loss.
