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.

为了在海水，海冰和海沙共存的复杂海洋环境中模拟高强度EH47船体钢的磨损和腐蚀行为，在实验室环境中使用摩擦计进行了加速磨损和腐蚀试验。研究了大载荷对在3.5wt％NaCl溶液中加冰和沙子以模拟海洋环境的磨损和腐蚀行为的影响。实验结果表明，摩擦系数（COF）随着工作负荷的增加而减小；同时，圆盘上的加载力和沙粒会强烈影响COF。3.5％（重量）NaCl溶液与沙子的摩擦机理以及磨损与腐蚀的耦合效应是磨损和腐蚀机理。此外，磨损机理发挥了主要作用。
