Summary

Ceramic and glass components with graded structures can be produced by means of electro-phoretic impregnation (EPI) of green bodies, prepared beforehand by electrophoretic deposition (EPD) or casting. In contrast to most of the common techniques components with continuously graded structures (graded pore size/density or/and graded chemical composition) are obtained. Steepness and dimension of the gradient could be adjusted reproducibly between some hundred microns and several millimeters up to centimeters. Examples are shown of silica glass green and sintered components with tailored gradient in density and pore size distribution as well as of composites of silica, alumina, ceria and zirconia with a functionally graded chemical composition. The impregnated green bodies were characterized by means of image analysis on the basis of SEM pictures and EDX analysis. The sintered components were characterized by optical spectroscopy. The influence of important process parameters of the EPI, like applied electric field strength, ζ-potential, viscosity, deposition time and pore size of the green body to particle size ratio, on the resulting graded structure is discussed.
