Fe-based materials have extensive applications in the building and automobile industries due to their excellent mechanical properties low cost. However, biomedical employment is restricted by corrosion propensity when contact with bodily fluids. In this study, single-step Plasma Electrolytic Oxidation, PEO, treatment Ta-rich electrolyte was used, for first time, improve resistance of low-carbon...

Abstract Over the last two decades, various methods have been developed for surface modification of Mg alloys among which plasma electrolytic oxidation (PEO) is one most effective tailoring properties. However, PEO coatings still need to be improved in aspects, including mechanical and corrosion performances. In current study, multi-walled carbon nanotubes (MWCNTs) were incorporated into a coat...

This study presents environmentally friendly and low-cost synthetic routes to produce antimicrobial coatings over 5052 Al alloy based on plasma electrolytic oxidation (PEO) technology. Two methodologies were explored: the decoration with copper anodic doping ions. The porous oxide layers produced in silicate media presented two consisting of γ-Al2O3 crystalline phase amorphous phases aluminosil...

UV treatments are commonly employed for removal of pollutants from water in industrial environments. Introduction a suitable photocatalyst can be beneficial improving the energy efficiency. This involves creating powerful reactive oxygen species that able to degrade pollutants. However, is required have both high surface area (accessible irradiation light source) and mechanically robust. TiO2 w...

A novel approach to surface modification was developed improve the corrosion performance of biodegradable magnesium alloys. Additively manufactured samples and Mg-Mn-based alloys were used in this study. This method involves combination plasma electrolytic oxidation create a porous ceramic-like matrix, followed by treatment with protective biocompatible agents. The most efficient for PEO-layer ...

This work investigates Reduced Titanium Oxide (RTO) in comparison with Carbon Cloth (CC) and commercial Boron Doped Diamond (BDD) as anodes hyperthermophilic bioelectrochemical systems operating at 80°C by Thermotoga neapolitana . Two samples of RTO were synthesized plasma electrolytic oxidation (PEO) titanium plates subsequent electrochemical reduction. Electrochemical performance CC, BDD, are...

In this study, duplex surface treatments were used to prepare a ZrO2/Cr bilayer coating on zirconium alloy cladding for enhancing the wear and corrosion behaviors. The cross-section morphology of coated Zr-4 was characterized; results show that Cr- ZrO2/Cr-coated samples had similar morphology, more obvious undulates could be observed than pure Cr owing rough plasma electrolytic oxidation coati...

Plasma electrolytic oxidation (PEO) has been targeted as an eco-friendly alternative technology to conventional chromic acid anodizing (CAA) for corrosion protection of aluminium alloys in the aircraft industry. However, PEO implies high energy consumption. Flash-PEO coatings (≤10 μm) produced short treatment times (≤ 5 min) constitute a feasible way overcome this limitation. Nevertheless, long...
