中文摘要:
      镁合金以其优越的性能在工业上的应用越来越广泛,但是其耐蚀性、耐磨性较差,硬度较低的缺点限制了它的大量使用。利用改进的金属蒸发弧放电离子源( MEVVA)在A231镁合金表面注入Ti离子,形成Ti离子注入改性层,以期提高镁合金表面的耐蚀性能。注入能量为45keV,注入剂量为3×lOn cm。2。注入后镁合金表面形成厚度约为450nm的注入层,用SEM、XRD分析了Ti离子注入层的表面形貌和相结构。用CS300P型电化学工作站测试了注入前后镁合金的耐蚀性,结果表明镁合金表面耐蚀性能显著提高。
英文摘要:
      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.
