Abstract

The effects of segregation of tramp impurities such as sulfur on metal/ceramic bonding is discussed. Microstructural and chemical information is given for the Fe/sapphire interface. The segregation behavior of the interface is evaluated between 500–800 °C. The interfacial structure is shown to be important to the segregation behavior. A possible link between the segregation of sulfur and interface void formation is presented.
