    Abstract: Generally speaking, the major parameter which has been used to monitor the dynamictribological properties of the films over the past decades is friction coefficient. However, it hasshown low in sensitivity for many cases. Therefore, it is necessary to introduce more improvedphysical measurements other than the friction coefficient to monitor and control the filmtribological characteristics in sliding contacts. In view of this, the novel technology of using insteadsurface magnetization variations for evaluating the wear-resistant properties of the films isproposed. The experiment was conducted by the pairs of SUS304 rubbing with SKD11 substratewith different TiN films (PVD and CVD) on the surface at different normal loads in dry frictionprocess. According to the experimental results of the dynamic variations of surface magnetizationand friction coefficient with the SEM observations of the wear tracks, the effects of normal loads onthe friction and wear properties for the die surfaces with different TiN films can be investigated.The experimental results show that the continuous surface magnetization variations can be used todetermine the timing of film fracture and the endurance life more accurately than that by the frictioncoefficient variations as usual. Therefore, the novel method of using surface magnetizationvariations does show great potentialities for evaluating the tribological properties of the die surfaceswith different TiN films.
