Biomedical Ti alloys free of vanadium and aluminum are receiving increasing attention due to the harmful nature of these alloying elements. For this reason, it has been proposed to replace them with more biocompatible elements such as Ta, Nb and Zr. The so-called resin metal alloys (Ti-Nb-Zr-Ta systems) refer to β-type Ti alloys, which are characterized by excellent biocompatibility and have an elastic modulus closer to that of human bone.
Open DownloadPlasma electrolytic oxidation (PEO) is a promising method for modifying metal surfaces by applying oxide ceramic coatings with appropriate physical, chemical and biological characteristics. Therefore, the goal of this study was to find the simplest settings that allow the creation of appropriate biologically active layers of implant surfaces on titanium implants using PEO.
Open DownloadThis work is devoted to modifying the surface of the Ti-13Nb-13Zr alloy by electropolishing and plasma electrolytic oxidation (PEO) in calcium-containing electrolytes: solutions of formate and calcium lactate (0.1–1.0 mol/m3) under a voltage of 200 V. and 400 V. As a result of the PEO process, a porous oxide layer containing embedded calcium compounds was formed on the surface of the Ti-13Nb-13Zr alloy.
