The formation process of a gradation in composition under a centrifugal force in functionally graded material (FGM) fabrication has been studied. The motion of ceramic particle in the viscous liquid, which corresponds to liquid metal, was analyzed by numerical calculation. The gradations of ceramic particle distributions in viscous liquid are visualized with the aid of computer graphics. Thses results are in good agreement with results of experiments which use the corundum/plaster model, including the size effect. Thus, the method of simulation presented in this study can properly estimate the gradation in composition. From the results of simulation and experiment using the model, it is also found that precise control of composition can be achieved by simultaneously using particles of different grain sizes.
