Generally, the continuous variations of the friction coefficient with sliding distance were unobvious and difficult to apply to monitor the tribological properties between the metal films. Hence, it was necessary to investigate another novel method. The original purpose of this paper was to appraise the practice and sensitivity of the above novel method. First of all, it was proved that the novel method was better for appraising the solid-film lubrication of the soft metal films. Combined the above results, a continuous model describing the tribo-electrification and wear mechanisms for a thin film of tin metal at different normal loads was proposed.
Moreover, since the value of the friction coefficient always showed positive, it was indiscriminative. By the continuous variations of tribo-electrification voltage with polarity that was positive or negative, it was possible to determine that friction occurs on which surface and which is the slider. Therefore, another purpose of this paper was to investigate the discrimination of this novel method. Furthermore, the novel method was better for apprising the wear resistance of the hard metal films. A continuous model describing the tribo-electrification and wear mechanisms for a thin film of nickel metal at different normal loads was also proposed.
Finally, the effects of the film-thickness on the variations of tribo-electrification were investiged in detail. To sum up, the experimental results can be widely used for designing the micro sensors in the future.
