The Microstructure and Abrasion Resistance of The Oxide Coatings on Ti-6Al-4V Produced by Plasma Electrolytic Oxidation in A Cheap Electrolyte

Abstract

A category of surface treatments, known as plasma electrolyte oxidation, has been employed to enhance the tribological characteristics of titanium and its alloys. The plasma electrolytic oxidation of Ti-6Al-4V alloy has been extensively researched. Energy Dispersive Spectroscopy (EDS), a scanning electron microscope (SEM), and mechanical tests (microhardness and wear) are used to identify the coating properties and morphology, and the phases produced are identified. Findings from an investigation into the TiO₂ layer on the Ti-6Al-4V alloy The findings showed that the MAO method enhanced wear resistance by (69.85)% and allowed for the deposition of layers with thicknesses ranging from 19.08 to 24.6 µm and high hardness (420 to 950 HV) in this research, the best results were obtained at the lowest possible cost and using low-cost equipment.
