Research Abstract

A powder spray stacking apparatus with a computer-controlling system has been developed for fine stacking of mixed ceramic/metal powders. Functionally gradient materials with a continuous microstructural transition from ceramics to metals have been successfully fabricated using this process followed by hot-isostatic pressing.
In the present process, metal and ceramic powders with different mixing ratios were mixed homogeneously in the suspension using ethanol as a solvent, and were sprayd onto a preheated substrate with continuously graded composition by the computer control. The deposited powder compacts were then cold-isostatically pressed, glass-encapsulated and hot-isostatically pressed. The microstructural observation showed that this process could precisely control the various composition profile with the minimum control size of 0.01mm in thickness. It has been shown that the metal/ceramic functionally gradient materials fabricated by the present process have larger fracture resistance and thermal shock resistance than the monolithic Zirconia ceramics.
