Elektrolityczne utlenianie plazmowe (POE) zastosowano do biomateriałów metalowych, takich jak niob i stop Ti-Nb-Zr (TNZ). Obróbkę prowadzono w elektrolicie kwasu H3PO4 z dodatkiem azotanu miedzi. Otrzymane porowate powłoki badano z użyciem SEM/EDX. Badania uzyskanych powłok wykazały, że są one wzbogacone w jony miedzi (ponad 3,5 %mas.), podczas gdy Cu/P oraz Cu/(P+osnowa) wynosiły odpowiednio 0,2 i 0,07. Taka charakterystyka sprzyja poprawie biokompatybilności badanego biomateriału.

EN

The Niobium and Titanium-Niobium-Zirconium (TNZ) alloy biomaterials were treated by Plasma Electrolytic Oxidation (PEO) in view of getting porous surface layers. For the PEO process, a special set up was built to perform the experiments in the electrolyte composed of concentrated H3PO4, with an addition of copper II nitrate. The surface layers were studied by means of SEM and EDS methods to reveal the effects of porosity and compositions. It was found one may create porous coatings on niobium and on TNZ alloy, enriched with copper ions. Over 3.5 wt% content of copper, with Cu/P and Cu/(P+Matrix) ratios equaling to 0.2 and 0.07, respectively, may assure a better biocompatibility of the biomaterials.
