本研究係以乙炔(C2H2)作為反應氣體，利用電漿輔助氣相沈積法製作類鑽碳膜於AISI 304不鏽鋼上，其中所沉積的膜厚分別為1、2及2.5 μm。接著，將傳統黑色、銀色烤漆及鍍類鑽碳膜的AISI 304不鏽鋼試片進行熱傳導的相關實驗。實驗係採用均勻熱源加熱以及點狀熱源加熱，而到達的控溫有30、40、50及60°C，並利用紅外線熱像攝影機量測試片溫度的變化。由實驗結果發現，類鑽碳膜確實可以提升散熱效率約 11%~ 47%。最後，本文以ANSYS有限元素軟體，分析點狀熱源加熱的溫度變化，其中的熱擴散係數係以實驗數據配合理論所計算出。在與實驗結果比較後發現，理論可合理的描述實驗結果。

In this study, the Acetylene (C2H2) is used as the reactive gas and the Plasma Enhanced Chemical Vapor Deposition is used to produce Diamond-like carbon film on AISI 304 stainless steel. The deposited film thicknesses are 1, 2 and 2.5 μm, respectively. Next, the traditional black, white paint and Diamond-like carbon film on AISI 304 stainless steel are conducted heat transfer experiments. Experiment adopts uniform heat source heating as well as point-like heat source heating. Temperatures of arrive are 30, 40, 50 and 60°C. The infrared thermal imaging camera is used to measure the temperature changes. Experimental results show that the Diamond- like carbon can indeed improve the heat dissipation efficiency of about 11% to 47%. Finally, the finite element software ANSYS is used to analyze the case of the point-like heat source heating. The coefficient of the thermal diffusivity is determined by the experimental data and theory. In comparison with the experimental results found that the theory can reasonably describe the experimental results.
