Since tribology is defined as a science and technology of friction and wear between two surfaces with relative motion, tribological phenomena are closely related to surface science. Tribological behaviors are strongly affected by the surface structure of moving contacts, on the other hand, the surface structure is dynamically altering by mechanical contacts, which is very complex and dynamically changing with time. Better understanding of tribological phenomena and development of tribo-systems are deeply dependent on advancement of fundamental research which is supported by a variety of modern surface analytical tools and research techniques in surface science using ultra-high vacuum and advanced surface analytical tools. In tribological phenomena, mechanical energy is supplied to contact surfaces, and so there are many phenomena which are waiting to be studied. Fundamental understanding of tribological phenomena on the bases of surface science provides the development of tribological technologies such as friction, wear and lubrication, and then contribute to develop new tribological technologies for energy saving, eco-friendly lubrication as well as improving the efficiency, safety, reliability and life of machines.
