<p>This invention relates to a method for forming a die for use in fabricating a ceramic honeycomb monolith structure having passages separated by walls having predetermined thicknesses. The method involves forming slots in the die and then applying a uniform coating of iron boride, chromium carbide, aluminum oxide, titanium carbide, titanium nitride or titanium carbonitride to the slot-defining surfaces of the die through CVD, the coating ranging in thickness up to 30 microns and being controlled in thickness to ± 1 micron.</p> |
