A new antibacterial Ca/P/Al containing coating

Synergistic Bactericidal Effect of Zn2+ Ions and Reactive Oxygen Species Generated in Response to Either UV or X-ray Irradiation of Zn-Doped Plasma Electrolytic Oxidation TiO2 Coatings

“…Compared to commonly used plasma spraying and magnetron sputtering, the PEO method involves the use of relatively simple equipment, has no restrictions on the sample size and shape, and is therefore easily scalable. The choice of electrolyte composition and technological PEO modes (temperature and processing time, electrical process parameters) have a significant impact on the thickness, roughness, porosity, microstructure, and phase composition of coatings. , The PEO layer usually consists of polymorphs of titanium oxides, such as anatase and rutile, and in the case of using complex electrolyte compositions or suspensions, it may contain Ca–P-based amorphous areas and nanoparticle inclusions. − The porous structure of PEO coatings containing Ca and P favored bone formation and showed higher bone maturation levels in an in vivo animal study …”
