随着对锆合金核材料使用性能要求的提高,对其耐腐蚀性能也提出了更高的要求。总结了常用包壳锆合金材料的耐腐蚀性能及其耐腐蚀性能的影响规律与作用机制,纳米材料的结构特征、腐蚀性能,以及影响其腐蚀性能的可能因素和影响机制,对锆合金纳米化后的耐腐蚀性影响因素进行了探讨。
With the demand of the using properties for zirconium alloys nuclear materials boost, the demand of zirconium alloys' corrosion resistance is much higher. This paper summarizes the corrosion resistance, the orderliness and the mechanism effect it, the structure of nano-materials and some nanocrystalline and their corrosion behavior, the possible factors and mechanisms affect the resistance corrosion. It also discusses factors of the corrosion resistance for the nanostructure zirconium alloys by nanocrystallization treatment.
