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.

Titanium-zirconium dioxide nanostructures loaded by hydroxyapatite were produced on the surface of Ti65Zr alloy. The alloy was treated anodization with subsequent immersion in calcium glycerophosphate (CG) solutions. resulting surfaces present TiO2-ZrO2 nanotubular (TiZr-NT) structures enriched (HAP). nanotube texture is expected to enhance surface’s corrosion resistance and promote integration bone tissue dental implants. TiZr-NT structure had a diameter 73 ± 2.2 nm length 10.1 0.5 μm. most favorable result for growth HAP Hanks’ balanced salt solution (Hanks’ BSS) obtained at CG concentration g/L. Samples soaked g/L demonstrated decrease contact angles 25.2°; after 3 days exposure BSS, further reduced 18.5°. studies also showed that = exhibited best stability.

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

Titanium (Ti) and Ti-based alloys are commonly used in dental implants, surface modifications of implants important for achieving osseointegration (i.e., direct connection between the implant bone). This study investigated effect an eco-friendly etching solution-a hydrogen peroxide-sodium bicarbonate mixture-on properties contact angles osteoblast adhesion proliferation on Ti surfaces. Disk-shaped specimens were prepared using different treatments (machining, sandblasting, sandblasting/acid-etching), they immersed solution ultrasonically cleaned. Surface characterization was performed scanning electron microscopy, digital angle analysis, X-ray photoelectron spectroscopy. MG-63 osteoblasts cultured specimens, their to specimen examined staining MTT assay, respectively. Additional with caused formation nano/micro hierarchical structures, increased roughness, enhanced hydrophilicity. Osteoblast found improve modified The method has potential enhance biological surfaces thereby performance.
