摘要
为了改善金属材料表面的综合性能,将表面改性技术和纳米技术相结合逐渐得到了人们的重视。用金属蒸气弧(MEVVA)源离子注入机,将能量为40keV,剂量为2×1017ions/cm2的Ti离子注入纳米纯铜中。利用透射电子显微镜(TEM)、X射线衍射仪(XRD)、俄歇电子能谱(AES)对表层组织及注入浓度分布等进行了分析。研究结果表明,纯铜表面经过SMAT纳米化处理后,注入元素的浓度呈现高斯分布,与未处理的样品相比,峰值浓度提高了30%,注入深度达到160nm。
To modify the surface properties of metal materials, more and more researches focus on the combination of surface modification and nanotechnology. Titanium ions were implanted into the copper by using MEVVA. Titanium implantation was carried out at the chosen ion doses 2 × 10^17 ions/cm^2 and the energy of 40keV. The surface microstructure and concentration distribution of implanted ions were characterized by using transmission electron microscope （TEM）, X-ray diffraetometer （XRD）, Auger electron spectroscopy （AES）. The results showed that the titanium element followed Gauss distribution and its maximal concentration of 25 % appeared at the depth of 45nm with the deepest implantation of more than 160nm.
