ABSTRACT:
A grain growth accelerator in a form dispersed in an aqueous solution or an organic solvent is introduced into a preliminarily fired body, and thereafter the preliminarily fired body is fired in a main firing process. In the main firing process, a volumetric diffusion of metal and grain growth of ceramic particles are caused as the firing temperature increases. Therefore, it is possible to manufacture a composite material which has such a gradient function that it is ceramic-rich on its surface and metal-rich in its inside, a high degree of surface hardness and toughness, and an interface-free structure.
