To improve the adaptability of GLC coatings in aqueous environment, a dense structure for GLC coatings was designed and constructed by nitrogen doping via PVD technique. The nitrogen content was tailored via tuning the nitrogen flow rate to optimize the tribological performances of the N-doped GLC coatings in water as well as to investigate the effects of different nitrogen contents. And the optimal nitrogen flow rate was 5 sccm. The results implied the nitrogen doping favored the increase of adhesion strength. The dense structure built by nitrogen doping entitled the N-GLC coatings to improved wear resistance in water and enhanced aqueous-adaptability, because the corrosion by water can be effectively inhibited compared with the column-structured nitrogen-free GLC coatings via PVD.

为了提高GLC涂层在水性环境中的适应性，通过PVD技术通过氮掺杂设计并构造了致密的GLC涂层结构。通过调节氮气流速来调整氮含量，以优化水中N掺杂GLC涂层的摩擦学性能，并研究不同氮含量的影响。最佳氮气流量为5 sccm。结果暗示氮掺杂有利于增加粘合强度。氮掺杂建立的致密结构使N-GLC涂层具有改善的水耐磨性和增强的水适应性，因为与通过PVD的柱状无氮GLC涂层相比，可以有效地抑制水的腐蚀。
