摘要
超高强度钢同时具有高强度和高韧性,是航空航天领域的重要承载构件,在飞机起落架、主梁、传动件、承力螺栓等领域有着广泛的应用。由于其使用时经常暴露在海洋大气环境下,腐蚀现象比较严重,通过对其进行表面保护,可以有效地改善其耐蚀、耐磨等性能,延长相关零件的使用寿命。针对目前常用的几种表面防护技术(热喷涂、真空镀、电镀、化学镀、表面组织转化、激光熔覆、离子注入等),综述了这些表面防护方法对不同超高强度钢耐磨、耐蚀、氢脆、疲劳等方面的影响,分析了这些防护方法的优缺点,并对其今后的发展方向进行了展望。
Ultra-high strength steel has both high strength and high toughness,making it an important load-bearing component in the aerospace industry,and thus it has a wide range of applications in aircraft landing gear,main beams,transmission components,load-bearing bolts,and other fields.Due to its frequent exposure to marine atmospheric environments during use,corrosion is quite severe.Through surface protection,the corrosion resistance,wear resistance and other properties of ultra-high-strength steel could be improved,which further extended the service life of the relevant parts.Herein,for the current commonly used several surface protection technologies(thermal spraying,vacuum plating,electroplating,chemical plating,surface tissue transformation,laser cladding,ion implantation,etc.),this paper reviewed the impact of these surface protection methods on different ultra-high strength steels in terms of abrasion,corrosion resistance,hydrogen embrittlement,fatigue and other aspects.Besides,the advantages and disadvantages of these methods were analyzed,and the prospects were made for its future develop-ment direction.
