Target preparation and characterization of interfaces in co-sintered metal ceramic composites using imaging and analytical Transmission Electron Microscopy

A new method for the production of metal-ceramics composites is co-sintering of a common produced green body. Detailed analysis of the interfaces is a precondition to understand the materials behavior and to align the process parameters for a reliable product. FIB-based target preparation enables a subsequent TEM observation. In addition to imaging preferred in STEM mode the elemental analysis using EDX and EELS leads to a comprehensive description of the interfaces.
