Abstract
A novel processing route is presented that is capable of manufacturing composites with continuous gradients in chemical composition. This route is based on an electrochemical gradation and subsequent infiltration of porous preforms and allows production of a variety of functionally graded materials and geometries. The method allows flexible adjustment of the retained gradients by adjusting experimental parameters. Relevant electrode kinetics are cast into a macroscopic model which provides a predictive capacity for the gradients obtained. Tungsten/copper gradient materials with different gradation profiles were produced and a comparison of the observed with the calculated gradients was carried out.
