碩士 === 崑山科技大學 === 機械工程研究所 === 97 === The tribo-electrification mechanisms had been successfully applied to monitor the tribological properties between the metal films by our laboratory members. 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. However, the above novel method is only suitable for the conducted materials. Therefore, this study is based on the above results to further develop another novel method for dynamic monitoring the tribological properties and chemical reactions by measuring the continuous variations of electrical contact resistance and friction coefficient between the self-mated titanium pairs under carbamide lubrication. The experiment was conducted by the self-developed friction tester and its measure system. Moreover, the wear loss was measured by an accuracy balance and the SEM was used to observe the micro structures of material transfer. Besides, EDS was used to analyze and clarify the material transfer. Similarly, the experimental results under carbamide lubrication were compared with that under water lubrication. All of the above dynamic monitoring results will be very helpful for the study of the related tribology engineering and the biomaterial materials in the future.
