摘要
随着核能的广泛使用，剩余乏燃料的储存已成为一个亟待解决的关键问题，尤其是如何有效吸收乏燃料在吸收中子时产生的中子辐射和二次γ射线。本研究采用冷喷法在 316 L 不锈钢上制备了 B4C/Al 和 W/B4C/Al 涂层。研究了涂层的微观结构和拉伸性能。采用蒙特卡罗方法模拟了两种涂层的热中子和二次γ射线吸收性能。结果表明，与 B4C/Al 涂层相比，W/B4C/Al 涂层由于 W 粒子的夯实效应而具有更好的机械性能。此外，由于添加了 W，二次 γ 射线吸收特性也得到了改善。
Cold-Sprayed W/B4C/Al Coatings for Neutron and γ-Rays Absorption
With the widespread use of nuclear energy, the storage of surplus spent fuel has emerged as a critical issue that needs to be solved, especially for the efficient absorption of neutron radiation and secondary γ-rays generated by spent fuel produced when 10B absorbs neutrons. In this work, B4C/Al and W/B4C/Al coating were prepared on 316 L stainless steel by cold spraying. The microstructure and tensile properties of the coatings were investigated. The performance of the thermal neutron and secondary γ-rays absorption of the two coatings were simulated using the Monte Carlo approach. The results indicated that, compared to the B4C/Al coating, the W/B4C/Al coating exhibited better mechanical properties due to the tamping effect of the W particles. In addition, the secondary γ-rays absorption property was improved due to the addition of W.
