| Abstract: |
| The magnesium alloy has broad application prospect in industry , but its poor property in corrosion resistance, wear resistance, hardness and so on, limits its application. Ti ion was implanted into A231 magnesium alloy surface by metal vapor vacuum arc ( MEVVA) implanter and formed a modified layer. This metal arc ion source had a broad beam and high current capabilities. Implantation energy was fixed at 45k eV and dose was 9 x l017 cm -2 Through ion implantation , Ti ion implantation layer approximately 400nm thick was directly formed on the surface of A231 magnesium alloy, by which its surface property was greatly improved. Microstructure, the component distribution and phase composition were analyzed using scanning electron microscopy ( SEM) and X-ray diffraction ( XRD) . The corrosion resistance of Ti ion implantation layer was studied by CS300P electrochemistry-corrosion workstation. The results show that the corrosion speed is obviously slowed down. The implantation layer has excellent corrosion resistance. |
