Head Mykhaylo M. Student, Доктор технічних наук Registration Date 24-12-2021 Organization Physico-Mechanical Institute named after GV Karpenko of the National Academy of Sciences of Ukraine popup.description1 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.  Product Description popup.authors Veselivska Halyna H. Hvozdetskyi Volodymyr M. Zadorozhna Khrystyna R.
