In order to ensure the safe and stable navigation of ships in the Arctic waterway, it is very important to search more convenient and environmentally friendly anti-icing methods for marine materials. In this paper,the brass and 6061 aluminum alloy as commonly materials used in ships were studied.By measuring the surface contact angles of the two metals at different temperatures, the relationship between contact angle and surface energy and dew point temperature were analyzed, and the variation tendency and mechanism of hydrophobicity with temperature variation were explored.The results show that the hydrophobicity of brass and 6061 aluminum alloy both decreases with the decrease of temperature and increases with the increase of oxidation degree on the surface, and the variation tendency of aluminum alloy is more stable than that of brass.
Key words： marine material; hydrophobicity; Arctic sea route; contact angle
