摘要 选用变形镁合金AZ31和铸造镁合金AZ91HP作为研究对象,进行强流脉冲电子束表面处理研究,这种处理能够有效地提高镁合金的抗蚀性和达到表面强化效果.处理后样品表面呈起伏形貌,出现典型熔坑,重熔层4 μm~10μm,导致表面出现塑性变形,主要是孪晶形式.由于镁的蒸发和第二相Mg17Al12熔化,表面形成铝的过饱和固溶体.性能测试主要是摩擦磨损和抗腐蚀性能测试.近表层几百微米范围内均出现显微硬度值升高的现象,改性样品平均摩擦系数降低,耐磨性提高.处理后样品在5%NaCl溶液中抗腐蚀性能有显著提高,镁合金强流脉冲电子束处理后,铝固溶度增加,表面易于形成致密的氧化膜,动电位极化曲线测量结果显示极化电阻增大,自腐蚀电流降低,最大可降低三个数量级,极化电阻与之相反.
