| Abstract: | Oxidation ceramic coatings were formed on 2024 alloy by micro--arc oxidation. SEM and XRD were used to characterize the microstructure and phase composition of the ceramic coatings. It is found that the coatings are relative dense and uniform, and mainly consist of α-Al2O3,γ-Al2O3 and amorphous phase. The nano--hardness of the ceramic coating gradually decreases from the interior to the surface of the coating along the ceramic coating. |
