Tribology is an interdisciplinary field that covers friction, wear, and lubrication, and has been developed to improve the properties of sliding surfaces of machines. In this paper, recent progress in tribology research is introduced with focusing on the development of analytical methods of solid-liquid interface. The role of tribology will be further expanded for the construction of energy-saving society in the future.
