摘要
A new method was proposed to design raw material powders on both the size distribution and the masses during the fabrication of functionally graded materials (FGMs) by co-sedimentation. This method was confirmed by producing Mo-Ti compositionally graded material and the experimental results show that it is fairly valid in the design of the particle size distribution of raw material. Analysis of the electron probe reveals that a smooth transition in composition through the thickness of the sintered body has been achieved and the tested values are fairly consistent with the design ones.
