Notes:
Ti ion and C ion is implanted into AZ31 magnesium alloy surface by metal vapor vacuumarc (MEVVA) implanter operating with a modified cathode. This metal arc ion source has a broadbeam and high current capabilities. Implantation energy is fixed at 45K eV and dose is 9×1017 cm-2and 3×1017 cm-2 respectively. Through ion implantation, Ti ion implantation layer approximately1000nm thick is directly formed on the surface of AZ31 magnesium alloy, by which its surfaceproperty is greatly improved. Microstructure, the component distribution and phase composition areanalyzed using scanning electron microscopy (SEM) and X-ray diffraction (XRD). The property ofhardness of the ion implantation layer was studied by HMV-1T Vickers micro hardness tester. Theresults show that Ti ion implantation layer of a magnesium alloy surface is mainly composed of TiO2,MgO and a little of TiO. The Ti-C double ions implantation layer is composed of MgO, TiC. Thehardness of ion implantation layer is improved
