摘要
飞机损伤的快速抢修是部队作战训练的需要,也是现代高技术战争确保空中优势、取得战斗主动权的重要保障。随着飞机结构新材料大量采用,传统的抢修技术难以适应要求。针对航空用钛合金、铝合金、复合材料及高温合金的战伤、磨损和腐蚀等失效特征,分析了传统飞机战伤抢修技术存在的不足,综述了国内激光加工技术在飞机损伤抢修中的应用研究进展。应用激光技术独特的优越性并引入功能梯度理念,把激光焊接、激光切割、激光熔覆应用于飞机的损伤抢修。其中包括飞机结构激光焊接修复、激光多层熔覆修复的合金粉末体系、组织特征、硬度分布规律、耐磨性和疲劳性能,飞机结构激光切割等。同时指出了飞机结构抢修领域有待解决的问题。
Rapid repair technique of aircraft damage is the requirement of military operations and training. It＇s also an important support to ensure the mastery of the air in modern high-tech war. With the development of new structural materials, traditional aircraft damage repair techniques have failed to meet the demands, with their shortages being analyzed. For its unique superiority, laser technique for the damages repair of aircraft structure is summarized, such as laser cutting, laser welding, and laser cladding used for battle field damage, corrosion and wear, including the conception of functional gradient material. Alloy powder system, microstructure, micro hardness regularities of distribution, resistance to wear and fatigue behavior of laser cladding are investigated. The merits of laser cutting are explained, and a mobile laser material processing system is introduced. Meanwhile, the need for further research is also briefly discussed.
