中文摘要 |
表面處理通常被應用於改善工具的使用壽命,類鑽碳膜(DLC)具有很多優越的性質,例如:高硬度、高磨耗阻抗、低摩擦係數及化學鈍性等等。氮氧化製程是在氮化完成的最後階段,利用空氣或水蒸氣處理,其利用水蒸氣為介質是一個整體性的重要步驟。本研究中,使用直流脈衝電漿化學沉積法,沉積類鑽碳膜(DLC)於氮氧化處理後之AISI H13工具鋼上;為了探討DLC薄膜的品質,我們利用拉曼分析、附著性測試以及硬度測試等,來檢測其性質。主要探討的直流脈衝電漿化學參數,包括不同的脈衝電壓。實驗結果顯示,氮氧化層深度可達0.05-0.06 mm(表面硬度為Hv0.05 1141),並可成功地在氮氧化處理後的試片上沉積1-2μm的類鑽碳膜。此外,使用脈衝電壓-1.5 kV、反應氣體CH4(5 sccm)、脈衝頻率1 kHz及工作週期10%,所沉積出的類鑽碳膜具有最低的ID/IG值(0.70)以及G-peak偏移位置(1543.31),其薄膜性質較佳。 |
英文摘要 |
DLC steel has many superior properties, such as high mechanical hardness, high wear resistance, a low friction coefficient and chemical inertness. The oxynitriding process uses air or steam at the end of the nitriding stage as an oxidizing medium. In this study, we prepared diamond-like carbon films after oxynitriding treatment of AISI H13 tool steel using DC-pulsed plasma CVD under various pulsed voltages. We used Raman spectroscopy analysis and adhesion and hardness tests to determine the properties of the DLC films. The experimental results showed that a 0.05-0.06 mm oxynitride layer (surface hardness was Hv0.05 1141), and 1-2 μm of DLC thin film could be obtained after the oxynitride/DLC duplex treatment. The duplex coating layers had the optimal properties when treated by a low pulse voltage (-1.5 kV), reactive gas of CH4 (5 sccm), 1 kHz pulsed frequency and the 10% duty cycle condition. The oxynitride/DLC duplex treatments possessed the lowest value of ID/IG (0.70) and offset of G-peak (1543.31). |
