摘要

为保证船舶在北极航道安全稳定地航行，寻找更便捷环保的船舶材料防冰覆方法极为重要.本文针对船舶常用金属——黄铜和6061铝合金进行实验，通过测量不同温度下两种金属的表面接触角，分析接触角与表面能关系以及露点温度的影响，探究其疏水性能随温度的变化趋势和机理.结果表明，黄铜和6061铝合金的疏水性能均随温度的降低而减小，随表面被氧化程度的增加而增强，其中，铝合金的变化趋势较黄铜稳定.

Abstract

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
