摘要	s: The present study elucidates the formation mechanism of Micro-arc oxidation film through a theoretical model that harmoniously integrates Micro-arc oxidation technology with density functional theory. XRD, EDS, and XPS analyses were conducted to ascertain the elemental composition and phase structure of the film layer products. Subsequently, based on the first principles of density functional theory, the phases involved in the film-forming reaction mechanism of the Micro-arc oxidized ceramic film were simulated, calculated, and analyzed. Ultimately confirming the reaction process products. The simulations exhibited a high degree of congruence with the experimental findings. The results indicate that during the Micro-arc oxidation reaction phase, O2 initially forms an Al2O3 passivation layer with the substrate. Subsequently, under conditions of high voltage and temperature, O2 reacts with SiC to produce SiO2 and CO2. When Ce(NO3)3 & sdot;6 H2O was introduced into the electrolyte, Ce3+ generates Ce(OH)3, CeO2, and Ce2O3 during the MAO process. Ultimately, CeO2 and SiO2 combine to form a stable composite oxide, CeO2 & sdot;SiO2. By computing the interfacial energy of each product, it was determined that the matrix preferentially establishes a stable contact with gamma-Al2O3. Through a combination of experimental and computational simulations, the generation mechanism of the Micro-arc oxidation reaction products has been deduced.
