To develop methods for the synthesis of hard anodic layers (Hard Anodic Coatings) with high durability and tribological characteristics on structural aluminum alloys.

popup.description2

A method for the synthesis of anode layers on the aluminum alloy AD0 has been developed, which consists in carrying out anodization in a classical electrolyte of 20% sulfate acid with the addition of 3-5% hydrogen peroxide. This method made it possible to increase the thickness of the oxide layer and its microhardness by 50%, abrasive wear resistance by 15%, wear resistance in a pair of friction with a steel ball by 30%. The equipment was modernized, which made it possible to carry out the process of hard anodizing of aluminum alloys in the temperature range -4 ... -8°С. A complex thermal treatment of the anode layers is proposed, which consists in heating the anodized samples to a temperature of 100-200°C, followed by boiling them. This operation stimulates the formation of high-temperature phases α-Al2O3 and ɤ-Al2O3 in the anode layer and doubles the abrasive wear resistance. The wear resistance of anodized samples in relation to alloy D16 increases 5 ... 10 times.
