Tribological behavior of plasma electrolytic oxidation layers synthesized on AMg6 and D16 alloys in couples with cast iron SCh 21–40

Abstract

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.
