Abstract

세라믹-금속간 접합을 위한 Au-Ni-Cr-Fe계의 접합 합금은 고온응용을 위하여 개발되어 왔다. 이 합금은 세라믹-금속간의 성공적인 접합에 반드시 필요한 낮은 항복강도, 높은 연성과 높은 인장강도를 보이고, 다른 접합 요소와 조화된 결합 성능(bonding performance)를 가진다. 이 접합합금은 고성능 고기능 접합체 형성을 위한 것으로 세라믹 엔진, 고온 연소기 내에서 사용되는 접합체에 이용될 수 있다.Au-Ni-Cr-Fe based alloys for ceramic-to-metal bonding have been developed for high temperature applications. This alloy exhibits low yield strength, high ductility and high tensile strength, which are essential for successful ceramic-to-metal bonding, and have bonding performance in combination with other bonding elements. This joining alloy is for forming high performance high performance joints and can be used for joints used in ceramic engines and high temperature combustors.
