摘要:
化学转化膜因其具有便捷、高效及成本低廉等优势，在航空领域得以广泛应用，对提升铝合金耐蚀性至关重要。然而，市售的铝合金化学转化剂普遍含高污染的六价铬盐，严重危害生态环境与人类健康。因此，开发绿色高效的铝合金化学转化替代技术已成为表面处理领域的重点研究方向。本文从化学转化膜成膜原理出发，综述了国内外无六价铬绿色化学转化技术的研究现状；结合转化膜制备工艺、成分、结构及成膜条件等参数，系统分析了几类环保型化学转化剂(包括三价铬、锆、钛、钒、钼、锂等稀土盐及有机转化膜)及其配套工艺的作用机制、性能特征与优缺点。在此基础上，总结了现有研究存在的膜层缺陷与耐蚀性不足等问题，并对新型无铬绿色化学转化技术发展进行了展望。
Abstract:
Chemical conversion coatings have gained widespread application in the aerospace industry due to their convenience, high efficiency, and low cost, playing a crucial role in enhancing the corrosion resistance of aluminum alloys. However, conventional conversion coatings for aluminium alloys often contain highly polluting hexavalent chromium salts, posing significant risks to the ecological environment and human health. Consequently, the search for green and efficient alternatives has become a key research focus in surface treatment. This review summarizes the current research status of hexavalent chromium-free green chemical conversion worldwide, beginning with the film-forming principles of chemical conversion coatings. The mechanisms, performance characteristics, advantages, and disadvantages of various green chemical conversion agents including trivalent chromium, inorganic salts (zirconium, titanium, vanadium, molybdenum, lithium, rare-earth salts ) and organic coatings with their supporting processes, considering parameters such as preparation, composition, structure, and film-forming conditions were analyzed. Furthermore, it summarizes existing challenges like film defects and insufficient corrosion resistance, and offers a perspective on the future development of novel chromium-free green chemical conversion technologies
