“…The results in the present paper are a continuation of our work presented in [10], in which porous and biocompatible coatings obtained on Ti6Al4V alloy biomaterial, enriched in bactericidal copper [33][34][35][36][37][38] and depleted in vanadium and aluminium ions, were described. In this article, the authors present the PEO coatings obtained on another very popular alloy, i.e.…”

In the paper, the fabrication method and characteristics of porous coatings on Ti-Nb-Zr-Sn alloy biomaterial obtained by plasma electrolytic oxidation (PEO) are presented. The PEO process was performed at two voltages of 180 ± 10 and 450 ± 10 V, respectively, during 3 min of treatment in the electrolyte based on orthophosphoric acid with copper II nitrate of initial temperature of 20 ± 2°C. Scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS), glow discharge optical emission spectroscopy (GDOES), Xray photoelectron spectroscopy (XPS) and 2D roughness measurements were performed on the samples. The study results indicate an enrichment of the porous layer (18 and 21 μm thick, for 180 and 450 V, respectively)

Ti and its alloys are the most commonly used materials for biomedical applications. However, bacterial infection after implant placement is still one of the significant rising complications. Therefore, the application of the antimicrobial agents into implant surfaces to prevent implant-associated infection has attracted lots of attentions. Scientific papers have shown that inorganic antibacterial metal elements (e.g. Ag, Cu, Zn) can be introduced into implant surfaces with the addition of metal nanoparticles or metallic compounds into electrolyte via micro-arc oxidation (MAO) technology. In this review, the effects of the composition and concentration of electrolyte and process parameters (e.g. voltage, current density, oxidation time) on morphological characteristics (e.g. surface morphology, bonding strength), antibacterial ability and biocompatibility of MAO antimicrobial coatings were discussed in detail. Anti-infection and osseointegration can be simultaneously accomplished with the selection of the proper antibacterial elements and operating parameters. Besides, MAO assisted by magnetron sputtering (MS) to endow Ti-based implant materials with superior antibacterial ability and biocompatibility was also discussed. Finally, the development trend of MAO technology in the future was forecasted.
