%X Plasma electrolytic oxidation (PEO) was performed on AA2024 aluminum alloy in an aqueous electrolyte containing 10 g/L sodium phosphate (Na3PO4) and 0.5 g/L potassium hydroxide (KOH), with and without the incorporation of zirconium silicate (ZrSiO4) particles at concentrations of 10 g/L and 20 g/L. The PEO treatments were conducted under two distinct electrical regimes: continuous direct current (DC) and pulsed DC. The resulting oxide coatings were systematically characterized using an array of analytical techniques to evaluate surface morphology, coating thickness, phase composition, wear resistance, corrosion resistance, and photocatalytic activity. The results indicated that both the presence of ZrSiO4 particles and the choice of electrical regime exert a pronounced influence on coating properties, particularly porosity, wear behavior, and photocatalytic performance. Coatings incorporating ZrSiO4 exhibited enhanced photocatalytic activity, with degradation efficiency exceeding that of particle-free coatings by approximately 10 %. However, the inclusion of particles did not universally improve wear resistance; in fact, under the continuous DC regime, coatings with particle additions displayed reduced wear resistance relative to their particle-free counterparts. With respect to corrosion resistance, all PEO-treated samples showed modest improvements compared to the uncoated AA2024 alloy.
