本研究主要探討P2O5-ZnO-SnO系列玻璃添加稀土元素對於Alloy 42接合性質之研究。實驗首先找出潤濕性較佳的P2O5-ZnO-SnO系統之組成成份,然後再添加氧化鑭稀土元素。將所得之玻璃使用以熱膨脹分析儀討論其軟化點溫度與熱膨脹係數是否產生改變。再以X光繞射儀確認是否再結晶,並對預先預氧化之Alloy 42放入預先升溫至450℃的熱處理爐中,持溫15分鐘進行接合。以SEM-EDAX確認玻璃與接合金屬間有無產生原子擴散以達到化學鍵結。再將接合後試片以剪力試驗探討其接合後之機械性質。
實驗結果顯示,添加稀土元素並不會導致P2O5-ZnO-SnO系統玻璃產生結晶。隨稀土元素添加量的增加,其軟化點溫度與熱膨脹係數上升、潤濕性會稍微下降,抗水解能力上升。以EDAX分析玻璃金屬接合處有微量原子擴散,進而強化了界面接合之效果。


Bonding properties of the ternary P2O5-ZnO-SnO glasses doped with rare earth element joined to the Alloy 42 were investigated. Starting from the best ternary P2O5-ZnO-SnO glass was selected to dope for La2O3, and the crystallization behavior was also studied by X-ray diffraction. Thermomechanical analysis was used to measure softening point temperature and thermal expansion coefficient. The joining between the preoxidized Alloy 42 and the glass was carried out by heating up to 450 ℃ for 15 minutes chosen as the best experimental conditions in terms of interface morphology. Energy dispersive X-ray analysis was used to obtain the concentration profiles of the elements present in the interfacial zone, meanwhile could confirm atomic diffusion from the metal to the glass whether achieves a good chemical bonding. The shear stress was tested to evaluate the mechanical property of the single lap joint.
The results indicated that even when a glass in the P2O5-ZnO-SnO ternary system doped with rare earth element, there was no tendency for crystallization to take place. An increase in rare earth element doping had an excellent anti-hydrolysis characteristic, but slightly decreased the wetting property. Furthermore, addition of rare earth element in glass was found increase their thermal expansion coefficient and softening point temperature. Analyses of Energy dispersive X-ray showed that a certain degree of atomic diffusion appeared meanwhile generally yielded good interface bonding.
