| 摘 要： | 微弧氧化膜层表面不均匀会对其应用产生影响,过去对其产生的原因研究很少.利用自制的微孤氧化电源在恒压模式下于硅酸盐电解液中对边长为100mm的正三角形纯铝件进行微弧氧化处理,利用涡流测厚仪、SEM分析以及电化学分析等对三角形顶角区域、边缘中心区域和中心区域的膜层厚度、形貌和性能不均匀性进行了表征.结果表明:微弧氧化层的相...

| Abstract: | AI substrates with regular triangular shapes(side length of 100 mm) were micro-arc oxidized in silicate electrolyte in constant voltage mode using a home-made micro-arc oxidation(MAO) power supply.The thickness,microstructure and corrosion resistance of the MAO coatings were investigated using a vortex thickness gauge,a scanning electron microscope and an electrochemical test rig.It was found that as-prepared MAO coating had nearly uniform phase composition,but its thickness varied greatly along with varyin... |
