Abstract
MXene, a novel two-dimensional layered material, finds extensive applications in solid lubrication. However, its practical use is limited by lubrication failures at high temperatures. To increase the service temperature of Ti3C2Tx solid lubricants, phosphate lubricating coatings were prepared using Ag@Ti3C2Tx as solid lubricants, which exhibits superior tribological properties. Compared with Ti3C2Tx phosphate coating, the friction coefficient and wear rate of Ag@Ti3C2Tx phosphate coating significantly decrease between 400 °C and 800 °C. Especially at 800 ℃, the friction coefficient of Ag@Ti3C2Tx phosphate coating reaches 0.09, and the wear rate shows extremely low. This study lays the foundation for the application of Ti3C2Tx in the field of solid lubricants across a wide temperature range.
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.
