【摘要】：为改善6061铝合金的表面耐磨性能和耐蚀性能,利用阳极氧化技术在草酸电解液中制备了阳极氧化膜。采用显微硬度仪测试了膜层的显微硬度,利用摩擦磨损试验机(CSEM)研究阳极氧化膜的摩擦性能,利用电化学阻抗谱(EIS)分析氧化膜的抗腐蚀性能。研究了阳极氧化电流密度、电解液温度以及阳极氧化时间对氧化膜的硬度、耐磨性及耐蚀性的影响规律,给出综合性能较好的阳极氧化工艺参数:电解液为40 g·L-1的草酸,阳极氧化温度为10℃,阳极氧化电流密度为1.0 A·dm-2,阳极氧化时间为120 min。
[Abstract]:In order to improve the surface wear resistance and corrosion resistance of 6061 aluminum alloy, anodic oxide film was prepared in oxalic acid electrolyte by anodizing technology. The microhardness of the film was measured by microhardness tester, the friction and wear properties of anodic oxide film were studied by friction and wear tester, and the corrosion resistance of anodic oxide film was analyzed by electrochemical impedance spectroscopy (EIS). The effects of anodizing current density, electrolyte temperature and anodizing time on the hardness, wear resistance and corrosion resistance of the oxide film were studied. The anodizing temperature is 10 鈩，
