Abstract Oxygen diffusion layers (ODL) on Ti-6Al-4V were produced by thermal oxidation at a temperature of 850 °C for three and six hours. ODL formation resulted in a β-Ti to α-Ti transformation, causing an increase in hardness. Polarization and EIS studies in stagnant and tribocorrosion conditions were performed under normal loads of 3–30 N in a phosphate buffered saline solution. In a stagnant condition, a passive bilayer film was formed on samples, which led to a low icorr. During tribocorrosion, the formation of a protective tribofilm resulted in a higher Ecorr and a lower icorr in ODLs compared with Ti-6Al-4V.

摩擦腐蚀过程中Ti-6Al-4V表面氧扩散层的生物腐蚀行为

摘要 Ti-6Al-4V 上的氧扩散层 (ODL) 是通过在 850 °C 的温度下进行 3 小时和 6 小时的热氧化而产生的。ODL 形成导致 β-Ti 向 α-Ti 转变，导致硬度增加。停滞和摩擦腐蚀条件下的极化和 EIS 研究是在磷酸盐缓冲盐水溶液中在 3-30 N 的正常负载下进行的。在停滞条件下，样品上形成了一层钝化双层膜，导致低 icorr。在摩擦腐蚀过程中，与 Ti-6Al-4V 相比，保护性摩擦膜的形成导致 ODL 中更高的 Ecorr 和更低的 icorr。
