To improve wear resistance and corrosion behavior of TC4 alloy, plasma electrolytic oxidation (PEO) was performed in a TiC particle containing electrolyte. Results show that increasing PEO current density is conducive to improving the coating thickness, promoting incorporation particles, enhancing coating. While content electrolyte reduces thickness. Under optimized condition, where has 2 g L−1 5 A dm−2, derived exhibits both high resistance. Moreover, it shown incorporated particles are more likely become components inner layer MAO

Plasma electrolytic oxidation (PEO) is a promising surface treatment for generating thick, adherent coating on valve metals using an environmentally friendly alkaline electrolyte. In this study, the PEO method was used to modify of AZ31 Mg alloy. The composite coatings were formed in phosphate-based electrolyte containing hydroxyapatite nanoparticles (NPs) and different concentrations (1, 2, 3, 4 g/L) TiO2 NPs. results showed that incorporation NPs increased porosity, thickness, roughness, wettability coatings. corrosion-resistance simulated body fluid (SBF) tested up 72 h all superior corrosion resistance compared bare substrate. Among samples TiO2, sample 1 g/L had highest inner layer (0.51 kΩ·cm2) outer (285 lowest average friction coefficient (395.5), so it best wear performance. antibacterial tests higher concentration NPs, lower adhesion bacteria, resulting enhanced properties against S. aureus. addition provided rate 97.65% coating.

Titanium (Ti) and its alloys have good biocompatibility, mechanical properties corrosion resistance, making them attractive for biomedical applications. However, their biological inertness lack of antimicrobial may compromise the success implants. In this review, potential micro-arc oxidation (MAO) technology to create bioactive coatings on Ti implants is discussed. The review covers following aspects: 1) different factors, such as electrolyte, voltage current, affect MAO coatings; 2) including cytocompatibility, hemocompatibility, angiogenic activity, osteogenic activity osseointegration; 3) antibacterial can be achieved by adding copper (Cu), silver (Ag), zinc (Zn) other elements achieve properties; 4) combined with physical chemical techniques enhance performance coatings. It concluded that offer new opportunities improving use in applications, some suggestions future research are provided.

The present study aims to explain how the incorporation of anatase TiO2 nanoparticles at three different concentrations, i.e., 1, 3, and 5 g/L, into ceramic-like oxide plasma electrolytic oxidation (PEO) coatings on pure titanium substrate can affect friction wear behavior in simulated body fluid (SBF) aqueous solution. For this purpose, a ball-on-disk tester was utilized characterize performance PEO coatings. morphology dimensions (width depth) tracks were analyzed by scanning electron microscopy (SEM) 2D depth profilometry, respectively. results indicated that abrasive identified all coatings; however, coefficient (COF), volume loss, rate strongly affected concentration nanoparticles. containing presented lower COF, less reduced rate, improved resistance due having smoother surfaces presence hard their inside pores. coating with 3 g/L demonstrated lowest value 1.33 × 10−6 mm3/Nm (about 32% reduction compared without nanoparticles) best protection properties among under investigation. findings suggest incorporated as promising choice surface treatment wherein load-bearing capacity implants is critical.
