In the mechanical system, where the phenomenon is happening all over the friction and wear, it is what is involved in the maintenance and simplified mechanical system efficiency and by clarifying the friction and wear phenomena. However, difficult in the variety of factors that are involved. It is unknown territory. Brake materials that require high-friction, wear resistance within it. Use the friction and wear, the phenomenon, exert its effect. Because it does not know the characteristics of tribology, it is the state in the development fumble brake materials. Therefore, the friction surface tried to clarify the mechanism of friction and wear that is observed in situ using a microscope mechanism.
