摘要
本文报道了以四硼砂(硼酸钠)为基料，在碱性电解液中用交流电阳极氧化铝的研究。在65℃下，用氢氧化钠调节硼砂溶液的pH值为10.5，电流密度为1.5 a dm−2，用50 g l−1硼砂溶液制备了厚度为11 μm的涂层。研究了镀液组成、温度、电流密度、阳极氧化时间和pH对氧化膜形成速度的影响，以及它们与阳极氧化电压和镀膜比的关系。
Studies on anodizing of aluminium in alkaline electrolyte using alternating current
The work reported in this paper concerns a study of the anodizing of aluminium in alkaline electrolyte based on borax (sodium tetraborate) using alternating current. Coating thicknesses of 11 μm were produced from 50 g l−1 borax solution the pH of which is adjusted with sodium hydroxide to a value of 10.5 at 65 °C, using a current density of 1.5 A dm−2. The effect of bath composition, temperature, current density, anodizing time and pH on the rate of build up of oxide coating and their relation to anodizing voltage and coating ratio were studied.
