Friction and Wear

Every moving parts are inevitably accompanied with friction and wear. Friction and wear have a great influence on durability and reliability of machines, therefore these friction and wear have to be understood thoroughly and the methods of friction and wear control are greatly required. However, the generation mechanism and prediction method of friction and wear are not established unlike lubrication mechanism, which brings about a lot of problems and difficulties in the industry. In order to understand the mechanism of friction and wear generation and to identify their characteristics, we have developed various friction and wear testers and performed friction and wear experiments for various materials by using them.
