ABSTRACT:
A method for producing by electrophoretic deposition multi-layer, polyfunctional, catalyst members for use in catalytic converters having a plurality of suitably porous and adherent catalyst support coatings of substantially uniform thickness, a plurality of non-identical catalytic agents imbued therein/on, and a flexible metal substrate, are disclosed. Such process involves maintaining electrical interaction between a metal substrate previously coated with catalyst-catalyst support material, the power source, and the electrodes disposed in the electrophoretic deposition ("EPD") cell containing a slurry of a second catalyst support material and a second catalyst composition non-identical to that found in the first catalytically-active layer.
