A sedimentation method is proposed to fabricate functionally graded materials (FGMs) with the continuous and smooth variations of composition. The relations between the compositional distribution of deposited body and the powder characteristics of raw materials as well as settling parameters are derived. Subsequently, the mathematical model of forming FGM based on the co-sedimentation has been established. At last, numerical simulations are conducted to explore the effects of the particle sizes of raw materials and suspension height on the compositional distribution of final products.
