Abstract
An extrusion die () including a plurality of pins () having side surfaces defining an intersecting array of slots () extending axially into the die () from a discharge face () of the die (). A plurality of feedholes () extend axially from an inlet face () of the die () opposite to the discharge face (). The feedholes () connect with the slots () at intersections () within the die () to create a flow path from the inlet face () to the discharge face (). A first coating () is on at least a portion of the feedholes () in a first zone () extending over a first axial length of the flow path. A second coating () that is different than the first coating () is on at least a portion of the side surfaces () of the pins () in a second zone () extending over a second axial length of the flow path. Methods of fabricating an extrusion die () and manufacturing a ceramic article (), such as a honeycomb body, are also disclosed.
