摘　　要：冷喷涂增材制造技术凭借其独特的“固态沉积”工艺特性,在航空损伤结构的修复再制造中表现出了广阔的应用前景。对于冷喷涂再制造的构件而言,其制造质量取决于基体界面的结合强度、沉积体内部的结构完整性及最终的加工表面质量。本文面向整个冷喷涂再制造流程,从基体表面预处理、冷喷涂沉积体的强化方法以及冷喷涂沉积体的后处理等方面介绍更具通用性的高性能冷喷涂再制造方法。此外,介绍了国内外航空领域现有的冷喷涂增材修复再制造案例,并对其在航空再制造领域尚存的问题与发展方向进行了展望。Cold spray additive manufacturing technology,with its unique"solid-state deposition"process characteristics,has shown great application potential in the repair and remanufacturing of damaged aerospace structures.For components remanufactured using cold spray,the manufacturing quality depends on the bonding strength at the substrate interface,the structural integrity within the deposition body and the final processed surface quality.This article focuses on the entire cold spray remanufacturing process,aiming to introduce more universal high-performance cold spray remanufacturing methods from three aspects:substrate surface pretreatment,strengthening techniques for the cold spray deposit,and post-treatment of the cold spray deposit.In addition,existing cases of cold spray additive repair and remanufacturing in the aerospace sector both domestically and internationally are introduced,and the remaining issues and future development directions in the field of aerospace remanufacturing are prospected.
