Abstract Optimized tribological properties including low coefficient of friction (COF) and wear rate are significantly affected by main factors such as hardness, toughness and tribochemistry. In this research, a series of TiMoCN coatings with duty cycle from 20% to 80% were prepared by multi-arc-ion plating (MAIP). Mo and C addition prominently promote comprehensive tribological properties of TiN coatings by solid solution strengthening, forming lubricating MoOx phase and grain boundaries (GB) amorphous-C phase, leading to phenomenal solid-lubricating and anti-roughening effect, which are enhanced as duty cycle rises, despite slight hardness decline (from 33 to 30 GPa).

脉冲偏置占空比对固体润滑TiMoCN涂层摩擦学性能的影响

摘要 包括低摩擦系数 (COF) 和磨损率在内的优化摩擦学性能受到硬度、韧性和摩擦化学等主要因素的显着影响。在本研究中，通过多弧离子电镀（MAIP）制备了一系列占空比为 20% 至 80% 的 TiMoCN 涂层。Mo和C的添加通过固溶强化显着提高了TiN涂层的综合摩擦学性能，形成润滑的MoOx相和晶界（GB）非晶-C相，导致显着的固体润滑和抗粗糙化效果，随着占空比的增加而增强尽管硬度略有下降（从 33 到 30 GPa），但仍会上升。
