Thermal chemical synthesis of nanostructured chromium carbide cermets

Nanocrystalline cobalt chromium carbide and nickel chromium carbide cermets are synthesized using the solution spray methodology followed by thermal chemical conversion. This newly developed synthesis approach is compared with traditional methods which have been used in carbide cermet industries. Characterization of as-synthesized materials is conducted by X-ray diffraction. Phase formations vs. processing temperatures are investigated. The structure and morphology of these materials are revealed by scanning electron microscopy and transmission electron microscopy.
