摘　　要：利用离子注入技术,分别采用单能量和多能量叠加注入方式在铀表面注入碳形成表面改性层,并对改性层的形貌、注入元素的分布和相结构分别进行扫描电镜(SEM)、俄歇电子能谱(AES)及表面相结构衍射谱(XRD)分析,利用电化学极化法测试注入样品的抗腐蚀性能。结果表明:离子注入碳能够提高铀表面抗腐蚀的能力。Using single energy or overlapped energy ion-implantation technology, a modified layer was formed after C ions implanted into uranium. The surface morphology, the structure of modified layer and depth distribution of elements in the surface layer of the uranium samples were analyzed by SEM, XRD and AES, respectively. The corrosion properties of the uranium samples were investigated by electrochemical polarization. The results indicate that anti-corrosive properties of the implanted uranium samples can be improved apparently.
