Summary: | 碩士 === 國立中興大學 === 材料工程學研究所 === 84 === This research focused on the interfacial reactions and the
microstructural changes in the Cu/Al2O3 system at 1000℃under
controlled atmosphere.Different types of Cu (foils, plates)/Al2
O3 (pellets, powders) samples were used in this study. The main
objectives of this research are listed below.1.Study of the
interfacial reactions: Oxygen partial pressures and time have
been varied. The resulted microstructural changes at the Cu/Al2
O3 interfaces have been studied by using optical microscopy,
scanning electron microscopy(+EDS) and X-ray diffractometer. The
reaction phases at the Cu/Al2O3 interfaces are consistent with
those predicted by thermodynamics.2.Thermogravimetric study. The
weight changes of samples were measured in air and in N2 by the
thermogravimetric analyzer. The relationships between the weight
changes and the reaction phase at the Cu/Al2O3 interfaces were
discussed.
