Abstract
MXene has been recognized globally for its ability to act as a solid lubricant, lubricant additive, and protective coating for enhancing the performance and longevity of dynamics systems. Ni3Al matrix composites have been fabricated through spark plasma sintering with varying Ti3C2Tx-MXene concentrations and slid against the Si3N4 ball to evaluate the lubrication potential at atmospheric conditions. The addition of MXene in the matrix has improved anti-friction and anti-wear properties attributed to the formation of a tribo-layer on encountering surfaces consisting of oxides and MXene’s fragments, as confirmed by TEM and Raman spectroscopy. However, further increasing MXene to 20 % led to an increase in friction, ascribed to the dominance of the hard TiC phase, which acts as a barrier for tribo-layer formation.
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.
