摘要(Abstract)：

采用固体粉末包埋渗铝法对AZ31镁合金薄板表面进行改性处理,增置富铝系改性层,选用常规的四辊轧机对表面改性后的AZ31镁合金薄板进行室温交叉轧制处理。利用XRD、SEM、光学显微镜和Corr Test腐蚀电化学测试系统等分析测试手段研究基体、轧制前和轧制后的渗铝试样表面的组织、性能演变情况。结果表明:轧制处理后富铝系改性层组织晶粒明显细小、均匀;轧制变形后富铝系改性层的耐磨性能略有提高,其表面显微硬度为63.5 HB,表面摩擦系数平均值约为0.6,表面摩擦磨损质量损失为0.26 mg;轧制变形后的富铝系改性层的耐腐蚀性能有较大的提高,其开路电位增加为-1.574 V,自腐蚀电位为-1.38 V,而自腐蚀电流密度提高一个数量级,为7.0×10-4m A/cm2。
