Zinc biodegradable implants represent a revolutionary advancement in medical technology, offering promising alternative to titanium and stainless-steel avoiding the need for secondary surgeries removal. In this study, we aimed fulfil clinical demand implant materials by applying coating of double-doped strontium copper resorbable tricalcium phosphate (SrCu-TCP) onto zinc-lithium (Zn-Li) alloy using Pulsed Laser Deposition method. The coated surfaces were thoroughly characterized X-ray Diffraction, Fourier Transform Infrared Spectroscopy, Atomic Force Microscopy, Scanning Electron Microscopy coupled with Energy Dispersive X-ray. Microbiology experiments conducted assess inhibitory effects on growth various bacteria strains, including gram-positive Staphylococcus aureus Enterococcus faecalis, gram-negative Pseudomonas aeruginosa Escherichia coli, as well fungus Candida albicans. obtained results showed that roughness Zn-Li increased from 91.8 ± 29.4 651.0 179.5 nm when SrCu-TCP. thickness ranged between 3–3.5 µm. inhibition all four strains was range 24–35% cultured SrCu-TCP samples. These findings suggest developed coatings are candidates applications requiring microorganisms.

Mg-Ca-Zn alloys are promising candidates for biodegradable medical materials. However, their high degradation rate hinders practical application. In this work, plasma electrolytic oxidation (PEO) with a fluoride-based electrolyte was performed on Mg-0.45Ca-xZn (x = 0, 0.45, 1.0, 2.0 wt.%) to enhance properties, and the coating characteristics, long-term performance, biocompatibility were studied. PEO coatings porous monolayer structures containing Zn element, while Mg-0.45Ca alloy bilayer structure dense inner layer outer layer. With increment of content in alloy, compactness adhesion strength improved, whereas chemical compositions hardness had no noticeable change. The performance investigated by electrochemical measurements simulated body fluid (SBF). results showed that all coated samples possessed decent anti-degradation properties. Among them, Mg-0.45Ca-1.0Zn Mg-0.45Ca-2.0Zn could provide excellent protection matrices over 3 months, which satisfied requirement All PEO-coated exhibited good Grade 0-1 cytotoxicity. Moreover, process enabled high-quality be formed bone screws. Coated superior study expected applied biomedical field.
