为满足核辐射屏蔽材料对结构-功能一体化的需求，采用大气等离子喷涂工艺在321不锈钢基体上设计并制备了 Fe-Ni-B 合金涂层复合材料，用于防护从裂变反应堆释放的中子与γ射线。在介绍该层状复合材料设计与制备的关键参数与技术细节的基础上，主要研究了层状复合材料对中子及γ射线的屏蔽性能。研究结果表明，该层状复合材料具有结构-功能一体化特征，理论计算及测试结果对比分析表明该材料对中子及γ射线拥有良好的综合屏蔽能力，有望在各种核辐射反应堆屏蔽系统中使用。
To meet the requirement of integrative mechanical and functional properties of shielding materials,a type of Fe-Ni-B alloy coating was designed and produced on typical 321 stainless steel substrate (1Cr18Ni9Ti) by air-plasma spraying technique.This sort of coating has normally been used as protection against neutrons andγrays emanating from fission reactors.The design and preparation of the Fe-Ni-B coating/SS substrate laminat-ed composite,and the relative key parameters and details had been described.The paper primarily investigated the radiation shielding abilities against neutron and gamma rays of the laminated composite,including the effec-tive ability for the slowing down of fast-speed neutrons,the attenuation ability against 60 Co and 137 Csγrays and absorption for 0.4 eV below thermal neutrons.The results indicates that the Fe-Ni-B alloy coating/stainless steel laminated composite by optimal APS procedure posses excellent integrative shielding effectiveness against thermal neutron,fast-speed neutron,andγrays,and has the potential to be applied in nuclear radiation shiel-ding devices.
