Abstract Cold spray technology is a promising solid-state, powder-based deposition methods for fabrication of coatings, near-net-shape manufacturing, and component repair. In recent years, this technology has been investigated for many applications in the nuclear energy sector. For example, it has been explored for the deposition of coatings of corrosion and oxidation materials on zirconium-alloys fuel claddings in light water reactors (LWR) for achieving more accident-tolerant fuel (ATF) cladding. Other examples of its use for nuclear energy applications include coatings for enhancements in wear resistance and heat transfer, near-net shape manufacturing of next-generation fuel claddings of oxide dispersion-strengthened (ODS) steels, and for mitigation and repair of potential chloride induced stress corrosion cracking in used fuel storage canister systems. This paper reviews published literature on the application of cold spray process for nuclear energy applications, while pointing to gaps that have yet to be addressed.

核能应用中的冷喷涂技术：最新进展综述

摘要 冷喷涂技术是一种很有前途的固态粉末沉积方法，可用于涂层制造、近净成形制造和部件修复。近年来，该技术已被研究用于核能领域的许多应用。例如，已探索在轻水反应堆 (LWR) 的锆合金燃料包壳上沉积腐蚀和氧化材料涂层，以实现更容错的燃料 (ATF) 包壳。其用于核能应用的其他例子包括用于增强耐磨性和传热的涂层、氧化物弥散强化 (ODS) 钢的下一代燃料包壳的近净成形制造、用于缓解和修复废燃料储存罐系统中潜在的氯化物引起的应力腐蚀开裂。本文回顾了有关冷喷涂工艺在核能应用中的应用的已发表文献，同时指出了尚未解决的差距。
