“…According to electron microscopic studies, the structure of the PEO layers synthesized on the D16T alloy is the segregation of pure copper precipitatesmicron and nano micro dimensions (Fig. 2) [3][4]. The pure copper in the PEO layer, synthesized on D16T, is obviously formed during the PEO process, then both aluminum oxide and copper oxide are formed simultaneously.…”

“…a b It was found that tribo structuresoxide films with the general formula FeAl2O4 (Fig. 2) were synthesized on the surfaces of cast-iron counter body after tests with PEO layers [6][7][8]. On the surface of the iron cast counter body in a friction couple with a PEO layer on AMg-6, the thickness of the oxide layer is significantly larger and is 3-5 microns.…”

“…Thanks to the PEO method, layers with increased hardness, wear and corrosion resistance are synthesized. However, insufficient study of the tribological behavior of the PEO layers constrains the introduction of this technology into production [1][2][3][4].…”

the tribological behavior of plasma electrolytic oxidation (PEO) layers synthesized on AMg-6 and D16T alloys (as the analogists of the A95556 UNWS USA and AA2024 ANSI USA) and on PEO layers formed on arc sprayed coatings (ASC) from both solid and cored wires (CW) in electrolyte-3 g /l KOH + 2 g / l Na2SiO3) by pulse current had been investigated. It has been established that the wear resistanse of the upper and lower PEO layers, synthesized both on the D16T alloy and on the ASC from the solid wire D16 is high. The highest wear resistance during friction with the fixed abrasive have PEO layers synthesized on the D16T alloy and on the ASC from D16 solid wire.The efficiency of the combination of arc spraying (AS) and PEO technologies for the reduction and hardening of surfaces of contact pairs (couples) from light alloys, operating both under conditions of abrasive wear and boundary lubrication is shown.

“…The synthesis of oxide layers on aluminum alloys by the method of plasma electrolytic oxidation (PEO) in weakly alkaline electrolytes can be an alternative to galvanic chrome plating. Oxide layers synthesized on aluminum alloys have a high hardness (1200 HV 0.2-2000 HV 0.2) and wear and corrosion resistance [7][8][9][10][11][12][13][14][15][16]. In addition, PEO layers synthesized on lightweight alloys have significant advantages over other coatings used in Metals 2019, 9, 280 2 of 14 friction units.…”

The different nature of the effect of hydrogen on the tribological behavior of two carbon steels (st. 45 and st. U8) upon their contact with super solid plasma electrolytic oxidation (PEO) layers synthesized on two light alloys (AMg-6 and D16T alloys as the analogists of the A 95556 UNS USA and AA2024 ANSI USA alloys correspondently) was investigated in the medium of mineral oil of the I-20 type. To compare the effect of hydrogenation on the tribological properties of the analyzed contact pairs, similar tests were also performed on the same mineral oil with clear water or an aqueous solution of glycerine added to its content. A spinel-type film (hercynite) was formed upon friction of two contacting surfaces—the iron-carbon steels and PEO layers synthesized on the AMg-6 alloy. This film was a reliable protection against wear of the surface subjected to the effect of hydrogen. When steels came into contact with the PEO layers synthesized on the D16T alloy, surface protection against wear was ensured by another mechanism. The phenomenon of selective metal transfer in the friction zone (from one to another friction surfaces) was revealed.

“…This is a comparatively new type of treatment and hardening of metal materials, which allows to receive multifunctional coatings with a unique complex of properties, including wear-, corrosion-, heatresistant, electrical insulating and decorative coatings. Arc spraying (AS) and PEO methods can be combined to repair worn parts from aluminum alloys and to strengthen the restored surfaces [1][2][3][4][5][6][7].…”
