With the target to improve the electrochemical and catalytic responses of Al alloy, the introduction of chemically inert phases of V₂O₅ in the coating is explored via both the direct nonreactive incorporation route utilizing V₂O₅ nanoparticles, and via in-situ reactive incorporation route using ammonium salt of metavanadate (NH₄VO₃). The Al2O3 formed during plasma electrolysis (PE) process is very suitable to form a substitution solid solution with V₂O₅, as both the Al⁺³ and V⁺⁵ ions have almost similar ionic radii. The formed solid solution upon cooling would be a promising coating layer with high electrochemical stability and inertness. Our investigation suggests that the in-situ reactive route of solid solution formation and PE coating can provide more stable and inert coating with an excellent electrochemical behavior despite the intrinsic porous nature of PE coating. The intrinsic porous nature of PE coating, however, provided catalytic activity making it a functionalized coating utilized for degradation of organic dyes, thus satisfying both structural and functional properties with a sort of trade-off efficiencies. The chemically inert incorporation of V₂O₅ is higher in proportion on substrate coating treated with NH₄VO₃ additive shown by EDS and XPS results and by the color differences of the coatings observed visually. The inert and stable compositions with higher thickness tend to improve its electrochemical behavior and the influence of V2O5 on coating structure, morphology, phase composition, physical appearance, and catalytic performance is discussed in details in this work.

以改善铝合金的电化学和催化反应为目标，通过利用V ₂ O ₅纳米粒子的直接非反应性掺入途径和通过原位反应，探索了涂层中V ₂ O ₅的化学惰性相的引入。使用偏钒酸铵盐（NH ₄ VO ₃）的引入途径。在等离子电解（PE）过程中形成的Al2O3非常适合与V ₂ O ₅形成置换固溶体，因为Al ⁺³和V ⁺⁵离子具有几乎相似的离子半径。冷却时形成的固溶体将是具有高电化学稳定性和惰性的有希望的涂层。我们的研究表明，尽管PE涂层具有固有的多孔性，但固溶体形成和PE涂层的原位反应路线可以提供更稳定和惰性的涂层，并具有出色的电化学性能。但是，PE涂层的固有多孔性质提供了催化活性，使其成为用于降解有机染料的功能化涂层，从而以一种折衷的效率满足了结构和功能特性。在用NH ₄ VO处理的基材涂层上，V ₂ O ₅的化学惰性掺入比例更高由EDS和XPS结果以及通过目测观察到的涂层的色差显示的_3种添加剂。具有较高厚度的惰性和稳定的组合物往往会改善其电化学性能，并且在本文中详细讨论了V2O5对涂层结构，形态，相组成，物理外观和催化性能的影响。
