随着海洋经济发展，海水环境中腐蚀与磨损导致的海洋装备零部件损伤问题日益严重。强韧与耐磨蚀一体化表面改性涂层是解决海洋环境损伤问题的关键技术。然而，传统硬质防护涂层普遍存在脆性强、韧性差的共性问题，极易在海水腐蚀与磨损交互作用下发生早期失效。磁控溅射高熵合金薄膜具有突出的耐磨损和耐腐蚀性能，已成为极具潜力的海水环境表面防护材料。然而，迄今高熵合金薄膜在海水环境中的腐蚀-磨损交互损伤机制仍不明晰，这制约了基于这一新型合金材料的强韧与耐磨蚀一体化薄膜的发展。本项目将系统研究海水环境中典型高熵合金薄膜的腐蚀-磨损交互损伤行为，揭示高熵合金薄膜海水环境腐蚀-磨损的物理化学本质，并借鉴贝壳高硬、高韧和耐腐蚀的结构特性，发展出新型的强韧与耐磨蚀一体化高熵合金/陶瓷仿生纳米多层复合薄膜，探索高熵合金仿生纳米多层结构的形成机制和强韧与耐磨蚀机制，为高熵合金薄膜在海洋领域的工程化应用提供理论依据和技术支持。

With the development of marine economy, damage to parts and components of marine equipment caused by corrosion and wear in seawater environment has become increasingly serious. Toughness and abrasion-resistance integrated surface-modifying coating is the key technology to solve the problem of marine environmental damage. However, the traditional hard protective coating has a common problem of strong brittleness and poor toughness, and it is easy to fail early under the interaction between seawater corrosion and wear. Magnetron sputtering high-entropy alloy film has outstanding wear resistance and corrosion resistance, and has become a surface protection material with great potential in seawater environment. However, the corrosion-wear interaction and damage mechanism of high-entropy alloy films in seawater environment is still unclear, which restricts the development of the tough and abrasion-resistant integrated film based on this new alloy material. This project will systematically study the corrosion-wear interaction and damage behavior of typical high-entropy alloy film in seawater environment, reveal the corrosion-wear physical and chemical properties of high-entropy alloy film in seawater environment, and learn from the structural characteristics such as high hardness, high toughness and corrosion resistance of shells. This is to develop a new type of tough and abrasion-resistant integrated biomimetic nano-multilayer composite film of high-entropy alloy/ceramic, and explore the formation mechanism of bionic nano-multilayer structure as well as the toughness and wear-resistance mechanism of high-entropy alloy, to provide theoretical basis and technical support for the engineering applications of high-entropy alloy films in the marine field.
