The Cu ions release was investigated by the work function by scanning kelvin probe (SKP), and the formation of CuO/Cu₂O was also researched by recording plasma discharges during plasma electrolytic oxidation (PEO) of Ti-14Cu alloy with different morphologies Ti₂Cu phase. It is found that L-Ti₂Cu phases with lower work function enhances the escape of Cu valence electrons from the 4 s energy level more easily compared to the G-Ti₂Cu and GL-Ti₂Cu phases. Consequently, this leads to earlier Cu ions released from L-Ti₂Cu phases as opposed to the G-Ti₂Cu and GL-Ti₂Cu phases. The earlier Cu⁺ released from L-Ti₂Cu phases increases the formation of Cu₂O and further oxidizes into CuO with increasing voltage, which lead to the enhanced the relative content of CuO. This enhancement contributes to improving antibacterial activity and tribocorrosion resistance due to stress response and lubrication effect by high relative content of CuO. This research provides a theoretical reference for the metal ions release of Ti-14Cu alloy in oxidation dissolution process of PEO and the formation of corresponding metal oxides.

通过扫描开尔文探针(SKP)的功函数研究了Cu离子的释放，并通过记录不同形貌Ti的Ti-14Cu合金在等离子体电解氧化(PEO)过程中的等离子体放电研究了_{CuO/Cu 2 O}的形成。₂ Cu相。研究发现，与G-Ti ₂ Cu和GL-Ti _{2 Cu相相比，具有较低功函数的L-Ti 2 Cu相}更容易增强Cu价电子从4s能级的逃逸。_{因此，与G-Ti 2} Cu和GL-Ti ₂ Cu相相比，这导致更早地从L-Ti ₂ Cu相中释放Cu离子。随着电压的增加，L-Ti ₂ Cu相中较早释放的Cu ^+增加了Cu ₂ O的形成并进一步氧化成CuO，从而导致CuO的相对含量增加。由于高相对含量的 CuO 的应力响应和润滑作用，这种增强有助于提高抗菌活性和耐摩擦腐蚀性。该研究为Ti-14Cu合金在PEO氧化溶解过程中金属离子的释放以及相应金属氧化物的形成提供了理论参考。
