摘要
To simulate the wear and corrosion behavior of high-strength EH47 hull steel in a complicated marine environment in which seawater,sea ice,and sea sand coexist,accelerated wear and corrosion tests were performed in a laboratory setting using a tribometer.The effect of large loads on the behavior of abrasion and corrosion in a 3.5wt%NaCl solution with ice and sand to simulate a marine environment were investigated.The experimental results showed that the coefficient of friction(COF)decreases with increasing working load;meanwhile,the loading force and sand on the disk strongly influence the COF.The mechanisms of friction and the coupling effect of abrasion and corrosion in the 3.5wt%NaCl solution with sand were the wear and corrosion mechanisms;furthermore,the wear mechanism exerted the predominant effect.
