Si{sub 3}N{sub 4} 和 Ag-Cu-Ti 钎焊合金之间边界处的反应产物已通过透射电子显微镜进行了表征。除了与 Si{sub 3}N{sub 4} 衬底相邻的 TiN 之外，还有先前未报道的正交 Ti-Si-Cu-N 化合物的连续层。还发现了额外的立方和六方 Ti-Si-Cu-N 相的证据；它们以离基底更远的孤立颗粒的形式存在。该立方化合物可能是在其他陶瓷-金属界面处观察到的那种{eta}型M{sub 6}X相。这些稀陶瓷以金属成分为主，是陶瓷-金属体系中常见的过渡相。
Reaction products at the boundary between Si{sub 3}N{sub 4} and Ag-Cu-Ti braze alloy have been characterized by transmission electron microscopy. Beyond the TiN adjoining the Si{sub 3}N{sub 4} substrate is a continuous layer of a previously unreported, orthorhombic Ti-Si-Cu-N compound. Evidence of additional cubic and hexagonal Ti-Si-Cu-N phases is also found; these exist as isolated grains farther from the substrate. The cubic compound is probably an {eta}-type M{sub 6}X phase of the sort observed at other ceramic-metal interfaces. These dilute ceramics, in which metallic constituents dominate, are common transitional phases in ceramic-metal systems.
