Abstract Ships sailing in the polar region will inevitably encounter sea ice wear. Frequent sea ice wear will affect the steel surface of polar ships and even threaten the safety of polar ships. In order to study the influence of low-temperature sea ice wear on polar ship steel, the 460 MPa class ultra-high strength polar ship steel was used as the research object to test the strength and plastic changes of the material under low temperature environment. The weight loss rate of the material wear under different environment was compared and analyzed by friction testing machine, and the surface morphology of the material after wear was observed. Further, the polar sea ice was simulated by professional equipment, and the environmental wear test of polar ship steel was carried out in the cold sea ice medium, and the reference data for the wear thickness loss of polar ship steel in the cold sea ice medium was obtained. The results show that with the decrease of temperature, the yield and tensile strength of ultra-high strength polar ship steel increase, while the plasticity decreases, and the hardness value doesn′t change significantly. The wear weight loss rate of the material is about 0.44E-05 g/(N·m) in seawater at room temperature, while it is as high as 1.90E-05 g/(N·m) in dry friction environment at -40 ℃, which is more than 4 times of that in seawater at room temperature. Under the simulated low temperature sea ice medium wear environment at -40 ℃, the polar ship steel is obviously worn by the sea ice medium, and the wear weight loss rate of the material is about 0.70E-05 g/(N·m). Under the condition of no protection, the surface thickness loss of polar ship steel is about 0.082 mm due to the wear of cold sea ice, which will cause great damage to the steel plate surface. Clarifying the influence of low temperature sea ice on the wear performance of polar ship steel has a positive role in promoting the development of new domestic polar icebreaker materials and accelerating the development of polar ship industry.
