Summary: One way to improve the characteristics of oxide coatings prepared by plasma electrolytic oxidation (PEO) method is to vary the properties of solid particles. In this study, the effect of particle crystallinity on the physicochemical properties and bioactivity of coatings on Ti and Ti6Al4V substrates was investigated. It was found that the crystallinity of particles had a specific influence on surface morphology and the pattern of particle incorporation, which ultimately affected the coating's bioactivity. Variation of particle crystallinity was proposed as a potential tool for adjusting PEO coating properties.

Summary: This study investigates the addition of fluoride to the electroless nickel-phosphorus plating solution to improve the corrosion resistance of MAO-coated AZ31B magnesium alloy. Fluoride reacts with Ni2+ ions and the MAO coating to form interphases, which enhance bonding and corrosion resistance. The presence of fluoride in the plating solution results in a more corrosion-resistant coating. The composition, structure, and morphology of the coatings are characterized using various analytical techniques, and their corrosion resistance is evaluated using different tests.

Summary: One of the main reasons for the premature failure of Ti-based implants is infections. Metal- and metal oxide-based nanoparticles have high potential for controlling infections. In this study, randomly distributed AgNPs-deposited onto well-ordered TiO2 nanotube surfaces were fabricated on titanium using anodic oxidation and electrochemical deposition processes. The AgNPs-deposited nanotube surfaces exhibited hydrophilic behaviors, which were beneficial for bone tissue growth. They also showed great corrosion resistance and improved electrochemical corrosion resistance compared to bare Gr2 surface. Additionally, the AgNPs-deposited nanotube surfaces exhibited antibacterial activity and high stability for long-term usage of implant applications.
