Ceramographic Analysis of Ceramo - Metal Bonding Interfaces

摘要

Two protocols are used for the methodology of ceramo-metal assembly: (ⅰ) the technique of transitional liquid state bonding (reactive brazing in a vacuum furnace) and (ⅱ) the solid state bonding method (thermocompression). Different reactions develop depending on nature of the materials and the method of bonding. The analysis of interfacial reactions presents difficulties because of the limited depth of reaction. I propose to present the experimental results obtained by different analytical techniques (SIMS, x-ray diffraction with grazing incidence with angles varying between 0.2 and 0.5°.
