Metal-Ceramic Composites Prepared through in-situ Decomposition of Transition Metal Nitrides

摘要

Co/ZnO and Ni/Al_2O_3 composites were prepared by in-situ decomposition of CoN_x and NiN_x during sintering, using CoN_x/ZnO and NiN_x/Al_2O_3 mixtures synthesized through an in-situ nitridation method as the starting powders. It was found that these composites showed a very uniform microstructure with metal particles homogeneously distributed among matrix grains. The microstructure and properties were tentatively studied.
