Abstract
The fabrication of a metal-ceramic gradient composite was studied to provide a fundamental idea for manufacturing functionally gradient materials in which chloride reduced metallic particles were infiltrated within a ceramic packing. The experiment using nickel chloride and alumina packing proved that the mixtures formed well controlled compositional gradient profiles. The infiltration process was successively simulated with the filtration theory which allowed the design of the optimal gradients. Attention has also been given to control designed gredients by using multi-layer packing composed of a different particle diameter.The mixing state of the compositional gradient mixture was evaluated by making use of the quality of mixing derived from information entropy theory. The mixing calculated from the nickel images observed under EPMA proved that the infiltration of chloride reduced particles could fabricate compositional gradient mixtures with a satisfactory amount of homogeneous mixing.
