| dc.description.abstract | 本研究是以擴散焊接技術(Diffusion-Bonding, DB)製作微流道預冷裝置為背景，應用於加氫站的高壓氫氣預冷卻系統中。研究以不同的擴散焊接參數，例如:溫度(temperature)、施加壓力(pressure)及時間(time)，並以不鏽鋼鈑JIS SUS 316L為材料進行層層堆疊接合。當擴散焊接完成後，先探討不同的擴散焊接參數對於試塊所造成壓縮量的大小，再找出影響擴散焊接後壓縮率的關鍵參數。接下來使用衝擊試驗來進行粗略焊接強度評估試驗，遭衝擊的擴散焊接試片若沒有因為衝擊形變而使擴散焊接面產生分離或剝離的情況，將視為通過粗略焊接強度評估試驗，若衝擊試驗中的所有試片均未因為形變而使擴散焊接面產生分離，這將很難斷定何種擴散焊接參數擁有較佳的接合質量及效果。故最後再以拉伸試驗來求得不同的擴散焊接參數下所得到的最大拉伸應力值(Max Load)，再由最大拉伸應力值及初始拉伸截面積共同求得各種擴散焊接參數試片之極限抗拉強度(UTS)，並將母材料同樣進行拉伸實驗後與擴散焊接試片做機械性質的比較，以求得各擴散焊接試片之接合程度，用以判斷何種擴散焊接參數擁有較佳的接合率。 | zh_TW |
| dc.description.abstract | This research is based on the diffusion bonding technology(DB), manufacturing micro-channel pre-cooling device as the background, applied to the high-pressure hydrogen pre-cooling system of the hydrogen refueling station. The research uses different diffusion bonding parameters, such as temperature, pressure and time, and uses stainless steel sheet JIS SUS 316L as the material for layer-by-layer bonding. After the diffusion bonding is completed, first discuss the amount of compression caused by different diffusion bonding parameters on the test block, and then find out the key parameters that affect the compression rate after diffusion bonding. Next, an impact test is used to conduct a rough bonding strength evaluation test. If the impacted diffusion bonding test piece does not separate or peel off the diffusion bonding surface due to impact deformation, it will be deemed to have passed the rough bonding strength evaluation test. None of the test pieces in the slabs caused the diffusion bonding surface to separate due to deformation, which makes it difficult to determine which diffusion bonding parameters have better joining quality and effect. Therefore, finally, the tensile test is used to obtain the maximum tensile stress value obtained under different diffusion bonding parameters, and then various diffusion bonding parameter tests are obtained from the maximum tensile stress value and the initial tensile cross-sectional area. The ultimate tensile strength (UTS) of the sheet, and compare the mechanical properties of the base material with the diffusion bonding test piece after the same tensile test to obtain the bonding degree of each diffusion bonding test piece to determine what kind of diffusion welding The parameter has a better joining rate. | en_US |
