碩士 === 崑山科技大學 === 機械工程研究所 === 94 === Variations of the tribo-electrification voltage had been successfully applied to monitor the tribological properties between the metal films and for appraising the solid-film lubrication of the metal films. Moreover, the novel method of using continuous tribo-electrification variations for monitoring the tribological properties between the soft metal films is more “sensitive” and “discriminative” than that by the continuous friction coefficient variations as usual. Therefore, this paper uses the self-developed reciprocating friction tester with the measurement system to investigate the tribo-spreading function between the metal films by measuring the variations of the tribo-electrification, the friction coefficient and the vertical displacement during the dynamic frictional process. Moreover, after the friction test; SEM is used to observe and to analyze the nano-wear structure and the composition. According to the experimental results, the noble method of using tribo-electrification variations for monitoring the tribo-spreading function between the metal films can be proposed. Since the above experimental procedures had been preliminary tested, this project can be investigated easily in the future. The results of this investigate have not only an original opinion, but it is also very helpful in the quality of machined products and in the manufacturing process of the film coating process.
