本文介绍了纯铌和钛合金（NiTi和Ti6 Al 4V）在含有300 g和600 g硝酸铜的1升浓磷酸溶液中，450 V，3分钟等离子体电解氧化得到的涂层的SEM和EDS结果。所获得的涂层是多孔的，并且主要由钛和铜中的磷组成。对于每个涂层，计算Cu/P比率。对于在含有600 g Cu（NO3）（2）在1 dm（3）H3 PO 4中的电解液中氧化的铌和Ti6 Al 4V合金，发现该系数的最大值等于0.22（wt%）。|0.11（at%）。对于在电解液中被PEO氧化的NiTi和Ti6 Al 4V合金，记录了Cu/P比的最小值，该电解液由300 g硝酸铜在1 dm 3的浓磷酸中组成，并且等于0.12（wt%）。|0.06（at%）。对于NiTi记录该比率的中间值，其等于0.16（重量%）。|0.08（at%）。
The SEM and EDS results of coatings obtained on pure niobium and titanium alloys (NiTi and Ti6Al4V) by Plasma Electrolytic Oxidation in the electrolytes containing of 300 g and 600 g copper nitrate in 1 litre of concentrated phosphoric acid at 450 V for 3 minutes, are presented. The obtained coatings are porous and consist mainly of phosphorus within titanium and copper. For each coating, the Cu/P ratios were calculated. The maximum of that coefficient was found for niobium and Ti6Al4V alloy oxidised in the electrolyte containing 600 g of Cu(NO3)(2) in 1 dm(3) of H3PO4 and equaling to 0.22 (wt%) | 0.11 (at%). The minimum of Cu/P ratio was recorded for NiTi and Ti6Al4V alloys oxidised by PEO in electrolyte consisting of 300 g of copper nitrate in 1 dm3 of concentrated phosphoric acid and equals to 0.12 (wt%) | 0.06 (at%). The middle value of that ratio was recorded for NiTi and it equals to 0.16 (wt%) | 0.08 (at%).
