The work investigated the effect of polytetrafluoroethylene (PTFE) on the tribological properties and corrosion resistance of epoxy/hydroxylated hexagonal boron nitride (EP/OH-h-BN) composite coatings. Results showed that the average friction coefficient and wear rate of the EP/OH-h-BN/PTFE composite coating with the mass ratio of PTFE to EP of 0.8 decreased by 68.4% and 60.3% compared to those of EP/OH-h-BN coating, respectively. Moreover, the coating still exhibited the largest |Z|_0.01 Hz value of 2.28 × 10¹¹ Ω·cm² after 80 days of immersion in 3.5 wt% NaCl solution, which was about 5 times of EP/OH-h-BN coating. The enhancement of coating properties was attributed to the synergistic strengthening effect of OH-h-BN and PTFE.

该工作研究了聚四氟乙烯 (PTFE) 对环氧树脂/羟基化六方氮化硼 (EP/OH-h-BN) 复合涂层的摩擦学性能和耐腐蚀性能的影响。结果表明，PTFE与EP质量比为0.8的EP/OH-h-BN/PTFE复合涂层的平均摩擦系数和磨损率较EP/OH-h-分别降低了68.4%和60.3%。 BN涂层，分别。此外，涂层仍然表现出最大的|Z|。在3.5 wt% NaCl溶液中浸泡80天后的_{0.01 Hz}值为2.28 × 10 ¹¹ Ω·cm ^{2 ，约为EP/OH-h-BN涂层的5倍。}涂层性能的提高归因于OH-h-BN和PTFE的协同强化作用。
