In addressing the challenge of enhancing orthopedic implants, 3D porous calcium phosphate (CaP) coatings on titanium (Ti) substrates modified with poly(lactic-co-glycolic acid) (PLGA) were proposed. CaP coatings on Ti were deposited using the ultrasonic-assisted micro-arc oxidation (UMAO) method, followed by modification with PLGA through a dip coating process at concentrations of 5%, 8%, and 10%. The addition of PLGA significantly improved adhesive-cohesive strength according to the scratch test, while PLGA to CaP adhesion was found to be not less than 8.

This paper presents the results of comprehensive research of micro-arc coatings based on diatomite-a biogenic material consisting of shells of diatom microalgae. The main focus of this study was the functionalization of diatomite-based micro-arc coatings by incorporating particles of titania (TiO) into them.

- The study focuses on modifying the surface of biodegradable Mg alloys by creating porous diatomite coatings using micro-arc oxidation at voltages between 350-500 V.
- The addition of ZrO microparticles to these coatings was investigated for its impact on their structure and properties.
- Results showed that while the coatings were mainly composed of small pores (<1 μm), higher voltages increased larger pores (5-10 μm), and the addition of ZrO significantly improved adhesive strength by 30% and enhanced corrosion resistance dramatically.
