Study on surface modification of nanocrystalline copper by Ti ions implantation
The combination of surface modification and nanotechnology was applied to modify the surface properties of metal materials. Titanium ions were implanted into the surface nanocrystalline copper by using metal vapor vacuum arc (MEVVA). Titanium implantation was carried out at the chosen ion doses 2×1017ions/cm2 and the energy of 40keV. The surface microstructure and concentration distribution of implanted ions were characterized by using transmission electron microscope (TEM), X-ray diffractometer (XRD), Auger electron spectroscopy (AES). The results showed that after the surface mechanical attrition treatment (SMAT) the microstructure of the surface layer may be refined into the nanoscale. The concentration of implanted ions followed Gauss distribution. The specimens after ion implantation have a remarkable enhancement of corrosion resistance with respect to the specimens without the surface treatment.
