In the paper, the Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray Spectroscopy (EDS) and X-ray Photoelectron Spectroscopy (XPS) results of the surface layer formed on pure titanium after plasma electrolytic oxidation (micro arc oxidation) at the voltage of 450 V are shown. As an electrolyte, the mixture of copper nitrate Cu(NO₃)₂ (10-600 g/L) in concentrated phosphoric acid H₃PO₄ (98 g/mol) was used. The thickness of the obtained porous surface layer equals about 10 μm, and it consists mainly of titanium phosphates and oxygen with embedded copper ions as a bactericidal agent. The maximum percent of copper in the PEO surface layer was equal to 12.2 ± 0.7 wt % (7.6 ± 0.5 at %), which is the best result that the authors obtained. The top surface layer of all obtained plasma electrolytic oxidation (PEO) coatings consisted most likely mainly of Ti₃(PO₄)₄∙nH₃PO₄ and Cu₃(PO₄)₂∙nH₃PO₄ with a small addition of CuP₂, CuO and Cu₂O.
本文展示了在450V电压下对纯钛进行等离子体电解氧化（微弧氧化）后形成的表面层的扫描电子显微镜（SEM）、能谱仪（EDS）和X射线光电子能谱（XPS）结果。作为电解液，使用了硝酸铜Cu(NO₃)₂（10 - 600g/L）在浓磷酸H₃PO₄（98g/mol）中的混合物。所获得的多孔表面层的厚度约为10μm，其主要由磷酸钛和氧以及作为杀菌剂嵌入的铜离子组成。PEO表面层中铜的最大百分比等于12.2±0.7wt%（7.6±0.5at%），这是作者获得的最佳结果。所有获得的等离子体电解氧化（PEO）涂层的顶层最有可能主要由Ti₃(PO₄)₄∙nH₃PO₄和Cu₃(PO₄)₂∙nH₃PO₄组成，并少量添加了CuP₂、CuO和Cu₂O。
