Abstract

Friction damage is always a major threat to the wide application of smart anticorrosion coatings. Here, the tribological properties of a smart Ti₃C₂T_x-based epoxy coating (MLT@EP) is adjusted by the reasonable collocation of mesoporous silica nanocapsules loading onto Ti₃C₂T_x-based plane (MLT). MLT@EP not only maintains good smart anticorrosion, but also has remarkable anti-friction and anti-wear properties. Its friction coefficient exhibits a low and steady trend, and the wear rate arrived at 1.14 × 10⁻⁵ mm³/N·m, which is decreased by 58.3 ∼ 93.3 % compared to control groups. The excellent tribological properties are mainly attributed to the synergistic effect of MXene-based lubrication film, high resistance to plastic deformation, and strong internal interaction.

基于 Ti3C2Tx 的智能环氧涂层的摩擦学性能：为解决传统智能涂层摩擦学性能薄弱的问题提供思路

摩擦损伤一直是智能防腐涂料广泛应用的主要威胁。本文通过在Ti3C2Tx基平面（MLT）上合理搭配介孔二氧化硅纳米胶囊，调整了Ti3C2Tx基智能环氧涂层（MLT@EP）的摩擦学性能。MLT@EP 不仅具有良好的智能防腐性能，还具有显著的抗摩擦和抗磨损性能。其摩擦系数呈低而稳定的趋势，磨损率为 1.14 × 10-5 mm3/N-m，与对照组相比降低了 58.3 ∼ 93.3 %。优异的摩擦学性能主要归功于基于 MXene 的润滑膜的协同效应、高抗塑性变形能力和强内部相互作用。

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
