Effect of large load on the wear and corrosion behavior of high-strength EH47 hull steel in 3.5wt% NaCl solution with sand

Journal Article


Abstract


  • 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.
