Abstract

The presence of atomic oxygen at internal metal-ceramic oxide interfaces significantly affects the physical properties of the interfaces which in turn affects the bulk properties of the material. This problem is addressed for the model system Ag-MgO from a phenomenological point of view using the finite element method. The performed parametric studies investigate the influence of different kinetic parameters of the diffusion-segregation system.
