摘要(Abstract)：

对3D打印AlSi10Mg合金进行阳极氧化处理，研究了氧化电压对其表面阳极氧化膜的结构特征、耐蚀性和耐磨性的影响。结果表明：与传统铸造高Si铝合金不同，3D打印AlSi10Mg合金晶粒尺寸细小，Si较为均匀地分布于铝合金基体内部，经阳极氧化处理后，膜层表面Si元素分布均匀，未发现明显Si偏析；随着氧化电压的升高，阳极氧化膜层的形核位点增多，生长速度加快，厚度增加，表面粗糙度降低，裂纹和孔洞等缺陷减少，致密性显著提高，同时膜层的硬度、耐蚀性和耐磨性也呈逐渐升高趋势；当氧化电压为16 V时，阳极氧化膜层的厚度为5μm,致密性最好，硬度高，相比AlSi10Mg合金基体，其耐蚀性和耐磨性显著提高。
