“…Для сплавов на основе вентильных металлов широкое распространение в поверхностной обработке получило плазменноэлектролитическое оксидирование (микродуговое оксидирование), в основе которого лежит образование прочных износо-и коррозионностойких оксидных покрытий с высокими адгезионными свойствами к подложке [1][2][3][4]. Для сталей и чугунов, титановых сплавов применимым является электролитно-плазменное диффузионное насыщение атомами легких элементов (химико-термическая обработка в электролизной плазме) с формированием на поверхности модифицированных слоев, состоящих из зон соединений и диффузионных слоев с измененным фазовым составом, которые обеспечивают улучшение механических свойств, повышение сопротивления коррозии и износу [5,6].…”

The paper discusses a possibility of increasing the wear and corrosion resistance of a low carbon steel surface after cathodic plasma electrolytic boronitrocarburising in a solution of boric acid, glycerin, and ammonium chloride, with the subsequent anodic plasma electrolytic polishing in an ammonium sulfate solution due to the formation of a modified structure consisting of a dense oxide layer and a diffusion layer below it, which contains up to 0.87% carbon, 0.80% nitrogen, and 0.87% boron upon reaching microhardness up to 970±20 HV. The competitive influence of the surface erosion under the action of discharges and high-temperature oxidation on the morphology and roughness of the surface is revealed. A positive effect of reducing the surface roughness during the formation of a dense oxide layer on the surface and a hardened diffusion layer under it on reducing the friction coefficient and mass wear, as well as reducing the roughness and additional oxidation of the surface during polishing on reducing the corrosion current density, has been established.

“…Numerous engineering coatings have been developed to enhance the friction and wear properties of the piston ring under severe operating conditions and prevent scratches [8][9][10][11]. The nitriding process has various advantages for piston rings, e.g., the wear amount and specific wear rate are reduced [12]. Additionally, a PVD-CrN coating can be deposited via cathodic arc technology.…”

The friction and wear properties, as well as the scuffing resistance, of different piston-ring coatings mating with a chrome-plated cylinder liner were investigated. Interrupted wear tests under the lubricant starvation condition were conducted to examine the wear behavior of Cr-diamond coating (GDC) and diamond-like coating (DLC). The results indicated that the DLC coating had outstanding tribological properties (small coefficient of friction and wear loss) at 150 °C, while the GDC coating exhibited better performance at an elevated temperature (240 °C). The DLC coating had a better scuffing resistance; no material adhesion occurred for 70 min under the unlubricated condition. The interrupted wear behaviors revealed that the scuffing process of the GDC coating involved the consumption of lubricant oil with relatively stable wear, a reduction in the friction force, and the occurrence of scuffing, in sequence. In contrast, although the friction force also increased after a short period of weak friction, no scuffing was observed. This is attributed to the formation of a mixed oxide and graphitic C tribolayer.

“…The effect of the anode plasma electrolytic saturation on some properties of steels after their boriding, nitriding, and nitrocarburising is studied. This treatment provides the change of wear mechanism from abrasiveadhesive wear to polishing mode [2]. Cathode plasma electrolytic nitriding (PEN) in a urea solution at 400-600С for 3-10 min reduces wear rate of cast iron G3500 by 2.5-fold and steel S0050A by 3fold after dry friction against WC balls as counter-bodies [3].…”

The opportunity of enhancement of the wear resistance of steel by combining anodic plasma electrolytic saturation of steel with interstitial elements followed by, quenching and plasma electrolytic polishing was shown. The samples of low-carbon steel were subjected to plasma electrolytic nitrocarburising. The samples of medium carbon steel were subjected to plasma electrolytic boriding. The formation of the modified layer including a hardened diffusion layer and a surface oxide layer occurs as a result of diffusion saturation. After nitrocarburising and boriding the steel samples were polished in an aqueous solution of ammonium sulphate. Conducting the surface polishing results in the removal of a loose part of the oxide layer (predominantly FeO), which reduces the surface roughness more than a half. Wear testing reveals that wear resistance of steel samples after polishing is higher than nitrocarburising ones of 1.8 times and boriding ones of 21.5 times.
