Abstract:Functionally graded materials have designed inhomogeneous distributions of different components on the scale of the material. They can be made by suspension processing, in which particles are stacked in a controlled manner. Segregation effects can be used to obtain the required gradient if the particles in suspension have different velocities. A model is derived for the composition profiles that develop as a result of these effects. The model can be used to determine the most suitable process conditions. The outcome of the model shows fair agreement with experiments found in the literature in which an Al2O3/ZrO2 composite has been produced by uniaxial centrifugal casting.
