以純金屬薄膜間微振幅及電位變化監控磨鍍薄層之研究
A study of using micro-amplitude and eletrification variations between pure metal films for monitoring the tribo-coating function
摘要
由於先前已成功發展摩擦帶電機制成為動態監控金屬薄膜磨潤特性的新方法，並且發現不管是就”靈敏性”或”判別性”之考量，上述這種新方法均優於傳統以摩擦係數監控的方式。 因此，本研究進一步利用自行研發之往復摩擦試驗機暨量測系統，於動態的摩擦過程中，量測摩擦帶電、摩擦係數及垂直變位(垂直方向之微小位移量)，以動態監控金屬薄膜之自行修復機能。並且，在摩擦試驗後，利用電子顯微鏡(SEM)觀察奈米級磨鍍(tribo-coating)之結構及組成成份。藉由實驗結果能提出以摩擦帶電機制動態監控金屬薄膜自行修復機能的新方法。 根據初步評估測試結果可知，同時量測摩擦帶電、摩擦係數及垂直變位的方式，確實可以精準監控金屬薄膜自行修復機能的過程。因此，本計畫不僅具有創新性及可行性，對於未來磨潤材料的學術研究暨薄膜加工的研發技術而言，其影響性更是不可限量。

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.
