Abstract
В заявке описан способ анодирования изделий из алюминия или алюминиевого сплава, в котором изделие из алюминия или алюминиевого сплава погружают в водный раствор при температуре от 0 до 140°С, предпочтительно от 0 до 130°С, причем раствор содержит серную кислоту, винную кислоту и по меньшей мере одну неорганическую соль элемента, выбранного из числа по меньшей мере одного переходного металла, лантаноида, актиноида и их комбинации, и прикладывают регулируемую разность потенциалов, в результате чего получают слои оксида алюминия, характеристики которых аналогичны или характеристикам пленок, полученных традиционным анодированием с использованием растворов хромовой кислоты, даже превышают их.
