This article presents the results of study of the influence of microarc oxidation parameters — ferquency and pulse duration — on the composition, properties of the coating, and also on the productivity of the microarc oxidation (MAO) process. It was found that the frequency in the range from 100 to 500 Hz significantly increases the formation rate of the MAO coating. A change in the composition and properties of the MAO coatings at pulse durations from 50 to 200 μs is observed. Starting with a pulse duration of 50 μs and a frequency of 400 Hz, the γ-Al2O3 crystalline phase is detected in the coating, the elemental composition, morphology, and microhardness of the coating change significantly.
