应用激光技术对铀上铌镀层进行表面合金化处理,并应用能谱和X射线衍射仪对处理层中的铌元素分布和相结构进行了分析。结果表明,铌元素沿处理层深度方向有一定的浓度梯度,距离处理层表面越近,铌含量越高;处理层中铌和铀相互作用生成了 相铀铌合金。
The surface alloying treatment of niobium on uranium was carried out by using laser technology. The distribution and phase structure of niobium in the treated layer were analyzed by energy spectrum and X-ray diffraction. The results show that niobium has a certain concentration gradient along the depth of the treated layer, and the closer the surface is to the treated layer, the higher the niobium content. In the treated layer, the interaction between niobium and uranium produces the uranium-niobium alloy.
