摘要

本實驗重量百分比68.8％Ag-26.7％Cu-4.5％Ti的銀銅基銲料作為氧化鋯(ZrO2)與純鈦(Ti)硬銲接合的填充材料，在Ar氣體的保護氣氛下，經過900oC以及950oC的溫度下分別持溫6分鐘、30分鐘、360分鐘，製作成三點抗折試片，並且製作對照組：1.氧化鋯(ZrO2)/Ag-Cu-Ti/氧化鋯(ZrO2) 2.純鈦(Ti)/Ag-Cu-Ti/純鈦(Ti)。
分別經過三點抗折機台測試，量測各組條件之下的最大的抗折強度(Bending Stress)，並且經由SEM/EDX元素分析其破斷面的組成結構，實驗結果顯示純鈦(Ti)/Ag-Cu-Ti/純鈦(Ti)的接合抗折強度最大，氧化鋯(ZrO2)/Ag-Cu-Ti/純鈦(Ti)與氧化鋯(ZrO2)/Ag-Cu-Ti/氧化鋯(ZrO2)的接合抗折強度接近，且短時間(6分鐘、30分鐘)硬焊接合強度會大於長時間(6小時)硬焊接合強度，此實驗最有趣的地方在於900度持溫6分鐘以及950度持溫6分鐘的氧化鋯(ZrO2)/Ag-Cu-Ti/純鈦(Ti)接合強度差異，會在結果討論中深入探討分析。

ZrO2 and pure titanium were joined by active brazing with 68.8%Ag-26.7%Cu-4.5%Ti(wt.) filler,at temperatures ranging from 900oC and 950oC for 6,30 and 360 minutes in argon atmosphere. Manufactured three-point-bending sample.And manufactured contrastive
sample:1.ZrO2/AgCuTi/ZrO2 2.Ti/AgCuTi/Ti.
After three-point-bending test,got bending stress from every sample,the microstructure in the fracture areas were investigated by SEM/EDS. The results were Ti/AgCuTi/Ti system has the biggest bending stress, ZrO2/AgCuTi/Ti system was close with ZrO2/AgCuTi/ ZrO2 system on bending stress, and short time(6,30min) brazed bending stress were bigger than long time(360min) brazed, the most interesting point is the difference at 900oC-6min and 950oC-6min ZrO2/AgCuTi/Ti system, and has detailed disscussion in Chap4.
