Surface texturing has gained significant attention over the last 30 years to tailor friction and wear
under various tribological conditions in fundamental and applied tribological systems. Under dry
conditions, surface textures help to improve friction or wear by reducing adhesion and the real area of
contact as well as trapping wear particles. However, especially under high load conditions, surface
textures rapidly wear away, thus losing their friction- and wear-reducing capability. A potential
strategy to improve their durability under more severe conditions is the combination with protective
solid lubricant coatings. In this regard, MXene nano-sheets are the most recent success story related to
2D materials as solid lubricant coatings. They appear particularly interesting due to their ability to
generate low-friction and wear-resistant tribo-films thus providing an excellent durability and wear
resistance. This aspect makes the combination of MXene solid lubricant coatings and surface textures
highly prospective. Therefore, this perspective aims at summarizing and analyzing the existing stateof-the art related to the combined use of surface textures and MXene coatings.
