説明

The motion of ceramic particles in a molten metal of a viscous liquid under a centrifugal force is numerically modeled to study the formation process of composition gradients. The simulated results are in good agreement with those of experiments that used a plaster-corundum model functionally graded material (FGM). It is found that greater gradients are obtained in cases of thinner thickness, greater applied centrifugal forces and smaller mesh size particles. In addition, the processing of mixed mesh size particles is examined. We conclude that the use of a mixture of particle sizes is particularly useful to control the composition of metal-ceramic FGMs manufactured by the centrifugal method.
