论文摘要
研究并讨论了通过血浆电解氧化获得的含沸石氧化物涂层的制备和特性。将纯天然（斜弯曲线）和合成（13倍）沸石固定在基于硅酸盐的电解质的铝支持上。获得的涂层是根据其形态，相和化学组成，光催化活性和抗腐蚀特性的特征。据观察，所提到的涂层的所有特性取决于处理时间和固定沸石的类型。与具有纯沸石的涂层相比，具有CE交换的沸石的涂层显示出更高的光催化活性和更有效的腐蚀保护。对于在脉冲DC状态处理的涂层中，观察到最高的光催化活性，含有30分钟，其中包含CE交换的13倍沸石，然后是含有CE交换的斜弯曲酸酯的涂层。明显的抗腐蚀特性具有几乎所有包含CE交换13倍沸石的样品。
The preparation and properties of zeolite-containing oxide coatings obtained by plasma electrolytic oxidation are investigated and discussed. Pure and Ce-exchanged natural (clinoptilolite) and synthetic (13X) zeolites are immobilized on aluminum support from silicate-based electrolyte. Obtained coatings are characterized with respect to their morphology, phase and chemical composition, photocatalytic activity and anti-corrosion properties. It is observed that all mentioned properties of obtained coatings are dependent on processing time and type of immobilized zeolite. Coatings with Ce-exchanged zeolite show higher photocatalytic activity and more effective corrosion protection than those with pure zeolite. The highest photocatalytic activity is observed for coatings processed in pulsed a DC regime for 30 minutes containing Ce-exchanged 13X zeolite, followed by those containing Ce-exchanged clinoptilolite. Pronounced anti-corrosion properties feature almost all samples containing Ce-exchanged 13X zeolite.
