Research Abstract

Ultra low friction and ultra high wear resistant hard coatings have keen attention for advanced automobile industries. Some new processes for the control of running-in process in friction were proposed and verified as promising processes with extra carbon thin overcoat on a-CNx coatings and irradiation of the ultra violet ray to the a-CNx coatings. Also new experimental method with compact friction pair system was proposed for the SEM observation of wear scar after repeated impacts.
