characterization of tribological and electrochemical corrosion behavior of go coatings formed on 6061 al alloy processed by plasma electrolytic oxidation

Plasma electrolytic oxidation (peo) is an electrochemical surface treatment process that is used to improve the properties of metal parts and components. the coating can provide a range of beneficial properties, such as increased hardness, wear resistance, and corrosion resistance, as well as improved adhesion and durability. plasma electrolytic oxidation (peo) improves aluminum alloy properties and adding nanoparticles to the electrolyte can further improve the surface properties, resulting in improved surface hardness, enhanced corrosion resistance, faster and more efficient process, and tailored surface properties. graphene oxide possesses unique properties such as high mechanical strength, excellent thermal conductivity, and remarkable lubricating abilities, which make it a promising candidate for improving tribological behavior. this study aims to examine the potential advantages of incorporating graphene oxide into coatings produced through the electrolytic plasma oxidation process.
