The effect of various cleaning methods on coating morphology and their effectiveness in removing organic contaminants has been studied this research. Bioactive coatings containing titanium oxides hydroxyapatite (HAP) were obtained through plasma electrolytic oxidation aqueous electrolytes molten salts. procedure for the coated surface was performed using autoclave (A), ultraviolet light (UV), radio frequency (RF), air (P), UV-ozone cleaner (O). samples characterized scanning electron microscopy (SEM) with an EDS detector, X-ray photoelectron spectroscopy (XPS), phase analysis (XRD), contact angle (CA) measurements. conducted studies revealed that from salt exhibited a finer crystalline structure (275 nm) compared to those (350 nm). After applying methods, carbon content decreased 5.21 at.% 0.11 which directly corresponds reduction contaminations decrease as follows: A > UV P O. This holds true both (25.3° 19.5° 10.5° 7.5°) (35.2° 28.3° 26.1° 16.6°). most effective moderate method is ozone treatment.

A simple method of synthesis TiO2 nanotubes (TiNT) loaded with hydroxyapatite (HAP) is described. Such find wide applications in various fields, including biomedicine, solar cells, and drug delivery, due to their bioactivity potential for osseointegration. The Cp-Ti substrate was anodized at a constant voltage 40 V, the subsequent heat treatment 450 °C. resulting TiNT had diameter 100.3 ± 2.8 nm length 3.5 0.04 μm. best result growth rate HAP Hanks’ balanced salt solution (Hanks’ BSS) obtained calcium glycerophosphate (CG = 0.1 g/L) when precipitates formed on bottom walls nanotubes. Structural properties, surface wettability, corrosion resistance, as an indicator coating have been studied. X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), potentiodynamic polarization test (PPC), electrochemical impedance (EIS), contact angle (CA) measurements were used characterize HAP-loaded (HAP-TiNT). CA, also serving indirect bioactivity, 30.4 1.1° not containing HAP. value HAP-TiNT produced g/L CG 18.2 1.2°, exposed BSS 7 days, CA 7.2 0.5°. studies measurement rates after 7-day exposure confirmed that processed exhibited most significant capacity formation compared other tested samples.

Coatings, Journal Year: 2024, Volume and Issue: 14(4), P. 376 - 376

Published: March 22, 2024

Ti and its alloys have received wide attention in marine engineering. However, the limited anti-biofouling capability may hinder their application. In present work, micro-arc oxidation (MAO) with without introduction of ultrasonic vibration (UV) has been conducted on metallic substrate an aqueous solution containing Na2Cu-EDTA to produce a Cu-modified TiO2 coating. Microstructural characterization reveals that UV increased thickness coating (ranging from ~13.5 μm ~26.2 μm) compared ~8.1 ~12.8 UV. A relatively higher Cu content (~2.13 wt.%) relative (~1.39 indicates enhances incorporation into TiO2. Further, both electrochemical properties response sulfate-reducing bacteria (SRB) were evaluated, revealing endows enhanced corrosion resistance antifouling capability. The results suggest ultrasound-auxiliary (UMAO) obviously surface performance for promising applications
