玻璃與金屬接合技術主要應用於需高度密封接合的元件,機械、光電、通訊、汽車、國防、航太及生醫等產業,都屬於此技術可應用的範疇。由於玻璃屬於脆性材料,而金屬則屬於延展性材料,在兩者熱膨脹係數相差極大的狀態之下,一般最常遇到玻璃與金屬間接合的問題為玻璃與金屬間的潤濕性不佳,或者是玻璃與金屬接合面受應力後的破壞。因此,如何強化玻璃與金屬間的接合強度,或是增加兩者接合界面的潤濕性,而使銲料能均勻填入接合面,便成為玻璃與金屬接合技術中最重要的課題。
本研究主要是應用三元活性銲料於750°C反應溫度接合Pyrex玻璃與304不銹鋼。在實驗中為提升Sn-Ti銲料接合後的強度,於二元Sn-Ti活性銲料中再分別添加不同的元素,如Al、Si、Cu、Ni等元素,形成三元活性銲料。使用高溫真空管形爐,將已塗好銲料的玻璃與不銹鋼的接合件加熱至750°C,以三元活性銲料所形成的銲道來接合玻璃與金屬。最後,以EPMA分析Al、Si、Cu、Ni等不同添加元素與錫鈦所形成的不同銲道組成的顯微組織,並以剪力試驗來確認其不同成份組成所形成銲道的強度。
The major applications of the glass jointing to metal are used to be the highly closely jointed components. The industries of the mechanical, the optic-electrical, the communication, the automobile, the national defense, and the biological-medical are also included in these applications. Glass is a brittleness material, and metal is a ductility material. The thermal-expansion coefficients of these two materials are not closely. The problem that we usually encountered is the bad wetting property on the joint between the glass and metal, or the joint interface between the glass and metal damaged after the stress. To enhance the joint strength between the metal and glass or add the soldering wetting to the joint area is an important study for the technical of glass and metal joint.
The purpose of this study is to use the three-phase solder reacting at 750°C to bond the pyrex glass and 304 stainless steel. During the jointing process of glass and stainless steel, we try to use the extra different soldering material into the Sn-Ti solder to enhance the mechanical strength of joint interface, we add the extra Al, Si, Cu, Ni respectively into the original Sn-Ti composition to form three-phase solder, then we use the three-phase solder to bond the glass and stainless steel at 750°C in a high temperature vacuum pump. Finally, we compare the Sn-Al-Ti, Sn-Si-Ti, Sn-Cu-Ti, and Sn-Ni-Ti solder in bonding the pyrex glass and 304 stainless steel respectively to understand their strength by Shearing Stress Test and the micro composition by EPMA.
