This paper presents the rolling contact fatigue method of evaluating the fatigue strength of substrate/hard film interface. The principle, set-up and applications of the dynamic adhesion tester were introduced. The results show that the measured bonding strength reflects the interfacial state of film-substrate system; it is sensitive to interfacial properties and insensitive to non-interfacial ones.
