摘　　要：核领域增材制造制品的抗腐蚀性能关乎反应堆系统的使用寿命和运行安全。本文通过归纳核领域增材制造制品腐蚀性能研究的基本概念,总结核领域增材制造制品的堆外腐蚀性能的研发现状,并基于核领域增材制造制品类型及激光粉末床融、定向能量沉积和激光近净成形等多种增材制造工艺的综合分析,探讨了核领域增材制造制品的腐蚀性能的特征,得出了由于增材制造制品制造工艺、材料再加工、腐蚀条件等不同,其抗腐蚀性能的表现也不同的结论,如掺杂少量铪、热等静压和固溶退火等材料后处理加工方式能提高核领域增材制造制品抗腐蚀性能。经综合论证分析,为了解、深化和拓展核领域增材制造制品腐蚀性能基础研究、技术手段和成果应用提供思路和方法借鉴。The corrosion resistance of additively manufactured products in the nuclear field is related to the service life and operation safety of the reactor system,so the corrosion resistance is very important.In this paper,the basic concepts of research on corrosion properties of additively manufactured products in nuclear field are summarized,and the research and development status of ex-core corrosion properties of additively manufactured products is summarized.Based on the comprehensive analysis of the types of additive manufacturing products in the nuclear field and various additive manufacturing processes such as laser powder bed fusion,directional energy deposition and laser engineered net shaping,the characteristics of the corrosion properties of additive manufacturing products are discussed.It is concluded that the corrosion resistance of additively manufactured products is different due to different manufacturing processes,material reprocessing and corrosion conditions,such as doping a small amount of hafnium,hot isostatic pressing and solution annealing,which can improve the corrosion resistance of additively manufactured products in the nuclear field.Through comprehensive demonstration and analysis,it provides ideas and methods for understanding,deepening and expanding the basic research,technical means and application of corrosion properties of additively manufactured products in the nuclear field.
