The effect of applied voltage (400, 450, and 500 V) on the microstructure, bioactivity, corrosion rate plasma electrolytic oxidation (PEO) coatings γ-TiAl alloy was investigated. microstructure chemical composition achieved were studied, along with their bioactivity behaviors in simulated body fluid (SBF). results demonstrated that higher coating′s surface pore, greater number suitable sites fo...

Magnesium (Mg) alloys have unique properties. However, their applications are limited in working environments due to poor corrosion resistance. Plasma electrolytic oxidation (PEO) is one of the most environmentally friendly and cost-effective ways that has been promoted treat Mg alloys. In this study, we investigated effect electrical parameters on microstructure, as well mechanical resistance ...

Adhesive bonding is a key joining technique for aluminium alloy components in the automotive industry. Plasma Electrolytic Oxidation (PEO) an emerging surface treatment protection of metal alloys including those aluminium. This work set out to assess adhesive bond strength and behaviour PEO coated AA6060-T6. Thin (15 25 μm) oxide coatings were produced on AA6060-T6 by electrolytic phosphate sil...

The surface characteristics of a dental implant doped with Si, Mg, Ca, and P ions via plasma electrolytic oxidation (PEO) were investigated using various experimental instruments. Plasma the alloy was performed in solution containing P, Mg at 280 V for 3 min. potentiodynamic polarization test porous conducted 0.9% NaCl solution. Si ion-doped HA films exhibited small large micro-pores uniform di...

Abstract Titanium (Ti) and its alloys are widely used as dental implant materials because of their high mechanical properties, biocompatibility, corrosion resistance. This research was undertaken to study the effect polymethyl-methacrylate (PMMA) sealing layer on performance plasma electrolytic oxidation (PEO)-coated titanium-based implants in pure saliva fluoride-containing solutions. The phas...

Plasma electrolytic oxidation (PEO) coatings on AZ91 Mg alloy were sealed in calcium nitrate solutions at different pH values (3, 4 and 5). Sodium dodecyl sulfate (SDS) was added to study the effect of SDS corrosion resistance coatings. The microstructure, chemical composition investigated by means SEM, XPS, XRD electrochemical tests. performance improved due precipitation Ca-containing precipi...

The growth of thin oxide coatings on the aluminum substrate in water-based sodium tungstate electrolyte by plasma electrolytic oxidation (PEO) is discussed and experimentally illustrated. carried out using a distinctive ultra-low duty cycle pulsed direct current (DC) power supply. During PEO processing elements present micro-discharges are identified standard optical emission spectroscopy (OES)...

BACKGROUND Search for materials that may either replace titanium dental implants or constitute an alternative as a new dental implant material has been widely studied. As well, the search for optimum biocompatible metal surfaces remains crucial. So, the aim of this work is to develop an oxidized surface layer on tantalum using plasma electrolytic oxidation (PEO) similar to those existing on ora...

In this study, a porous oxide layer was formed on the surface of 316L stainless steel (SS) by combining Ti magnetron sputtering and plasma electrolytic oxidation (PEO) with the aim to produce a polymer-free drug carrier for drug eluting stent (DES) applications. The oxidation was performed galvanostatically in Na3PO4 electrolyte. The surface porosity, average pore size and roughness varied with...
