Anodizing under conditions of oxygen activation of the inter-electrode gap

Structured alumina is currently used in a wide range of applications. Interest surface with wear-resistant coating motivates creation methods for high-speed oxidation an increase the thickness and hardness layer, obligatory observance environmental parameters decrease energy intensity production. Considering activity aluminum towards oxygen, very important aspect search conditions to natural oxide film level functional significance. The generally accepted scheme classical anodizing represents closed system electrolytic cell, inside which elements are activated interelectrode gap state ionic excitation under action electric field. efficiency interaction depends on medium’s nature variability volt-ampere parameters. This work proposes different mechanism intensifying process. Oxygen outside cell allotropic state, form ozone, transmitted into gap. phase composition, structure, thickness, microhardness investigated. aim research establish effect ozone
