Abstract
Solutions to the problem of washcoat and/or overcoat adhesion loss of ZPGM catalyst on metallic substrates are disclosed. Present disclosure provides a novel process for improving WCA to metallic substrates of ZPGM catalyst systems. Reduction of WCA loss and improved catalyst activity may be enabled by the selection of processing parameters determined from variations of pH and addition of binder to overcoat slurry, and particle size of washcoat. Processing parameters may be applied to a plurality of metallic substrates of different geometries and cell densities.
