Consideration of TOMOGANE in some kinds of mechanical elements

Abstract

Rubbing between the same kinds of metals shows large frictional force and causes adhesive wear. Its behavior is called TOMOGANE in Japan. We studied TOMOGANE as follows: ballscrew, linear ball guideway, rolling bearing and fastner. For example, we made the experiment using aluminum oxided bolt and aluminum nut which showed large torque and adhesion in the pure water.
