The incorporation of tungsten oxides on the surface of the oxidized aluminum alloy was investigated. Deposition was carried out in two ways – during the process of plasma‐electrolytic oxidation (PEO) and by impregnation of the oxide in solutions of tungsten salts. The experimental program was performed using a central composite rotatable planning. It is established that the amount of tungsten oxides in coatings obtained by PEO in mixed silicate‐tungstate electrolyte is 50 times higher than in coatings received by PEO in silicate electrolyte with following soaking in WO₄²⁻ containing solutions.

氧化铝基质对钨和氧化硅的比较吸附

研究了在氧化铝合金表面上掺入氧化钨。沉积以两种方式进行-在等离子电解氧化（PEO）过程中以及通过在钨盐溶液中浸渍氧化物。实验程序是使用中央复合旋转计划执行的。可以确定的是，在含WO ₄ ^2-的溶液中浸泡后，PEO在硅酸钨-钨酸盐混合电解质中得到的涂层中氧化钨的量是PEO在硅酸盐电解质中得到的涂层的50倍。
