Abstract
The motion of ceramic particles in a molten metal of a viscous liquid under a centrifugal force is numerically modeled to study the formatio n 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 gradient s are obtained in cases of thinner thickness, greater applied centrifu gal forces and smaller mesh size particles. In addition, the processin g of mixed mesh size particles is examined. We conclude that the use o f a mixture of particle sizes is particularly useful to control the co mposition of metal-ceramic FGMs manufactured by the centrifugal method .
