ABSTRACT Because of a great variety of tribocomponents and lubricants, the phenomenon of frictional magnetization and electrification between tribocomponents becomes more obvious. In order to understand the effects of frictional magnetization and electrification on tribology characteristics and miniature electrical control component signal, the frictional magnetization and electrification test under dry friction condition is investigated by the reciprocating electrification tester. Three material-pair types will be investigated their frictional magnetization and electrification behavior under various operating parameters, e.g. driver speed, normal load, and sliding distance. Moreover, the worn surface will be observed by the optical microscopy and SEM. Results show that the magnetization and electrification on friction surfaces increases with increasing load, and decreases with the carbon content of a material, and depends on material-pair. It is found that wear particles have been magnetized on the friction surface, even that the wear particles has been adhered to the surface caused by electro static action. Moreover, in the microscopic view, the frictional magnetization and electrification are related to both friction and wear.
