| Summary: | 碩士 === 國立交通大學 === 材料科學與工程學系 === 98 === 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.
