“…As can be seen from the data obtained, the coating formation process begins with the formation of the γ-Al 2 O 3 phase. An increase in the processing time leads to the appearance of α-Al 2 O 3 as a result of the thermodynamically favorable polymorphic transformation γ-Al 2 O 3 →α-Al 2 O 3 [47]. It can be seen that with an increase in the KOH content, the ratio of the volumetric content of γ-Al 2 O 3 and α-Al 2 O 3 phases changes towards a relative increase in the α-Al 2 O 3 phase.…”

“…These factors can be attributed to two types, called: external and internal. External factors include (composition and temperature of the electrolyte; electrical parameters -voltage, frequency and shape of pulses, cathodic and anodic current densities, process duration), and internal factors include (alloy composition and heat treatment, surface roughness, base porosity) [19,20]. These factors determine such characteristics of MAO-modified surfaces as the integral thickness and thickness of individual layers, elemental and phase composition, structure and density of modified layers [21,22].…”
