Due to low density and high specific strength, titanium alloys have been widely used for marine applications. However, the severe wear and corrosion of titanium alloy components is still a problem. To alleviate this problem, protective coatings are applied. In here, the influence of Mo content on the protective performance of CrMoCN coating for Ti-6Al-4V substrate has been investigated. The short- and long-term corrosion resistances of coating in artificial seawater are studied using an electrochemical workstation with three-electrode configuration. The tribological behaviors of CrMoCN coating sliding against Al₂O₃ ball are evaluated using a ball-on-disk tribo-meter. The results reveal that the CrMoCN coated samples have higher wear- and corrosion-resistances than the bare substrate. The CrMoCN coating with 8.1 at.% Mo displays the highest values of OCP (0.22 V), R_ct ((8.639 ± 0.270) × 10⁷ Ω·cm²) and R_p ((3.04 ± 0.24) × 10⁶ Ω·cm²). However, their protective performances are degraded in the long-term, and then the R_p of CrMoCN-2.5 coating continuously decreases from (5.99 ± 0.47) × 10⁵ Ω·cm² at 7 days to (0.13 ± 0.01) × 10⁵ Ω·cm² at 35 days. With an increase in the Mo content, the friction coefficient of CrMoCN coating/Al₂O₃ tribopair decreases from 0.36 to 0.31 while the coating wear rate increases from 4.65 × 10⁻⁷ mm³/Nm to 1.01 × 10⁻⁶ mm³/Nm.

由于低密度和高比强度，钛合金已被广泛用于海洋应用。但是，钛合金部件的严重磨损和腐蚀仍然是一个问题。为了减轻这个问题，应用了保护涂层。在此，研究了Mo含量对CrMoCN涂层对Ti-6Al-4V衬底的防护性能的影响。使用三电极配置的电化学工作站研究了人造海水中涂层的短期和长期耐腐蚀性。CrMoCN涂层在Al ₂ O _3上滑动的摩擦学行为使用圆盘摩擦计对球进行评估。结果表明，CrMoCN涂层的样品比裸露的基材具有更高的耐磨性和耐腐蚀性。所述CrMoCN 8.1涂覆在。％的Mo显示OCP（0.22 V）的最高值，R _CT（（8.639±0.270）×10 ⁷  Ω·cm的²）和R _p（（3.04±0.24）×10 ⁶  Ω·厘米²）。然而，它们的保护性能劣化在长期，然后将R _p的CrMoCN-2.5涂覆连续地从（5.99±0.47）×10降低⁵  Ω·厘米²在7天（0.13±0.01）×10 ⁵  Ω·cm ²在35天时。随着Mo含量的增加，CrMoCN涂层/ Al ₂ O ₃摩擦副的摩擦系数从0.36降低到0.31，而涂层磨损率从4.65×10 ^-7  mm ³ / Nm增加到1.01×10 ^-6  mm ³ /嗯
