Abstract: Methods of depositing an inorganic material on an extrusion die including positioning an extrusion die within a vapor deposition chamber, positioning an impedance disk over a face of the extrusion die, the impedance disk having a plurality of through holes and the face of the extrusion die having a plurality of slots defined by a plurality of extrusion die pins, and flowing one or more deposition gases through the plurality of through holes and into the plurality of slots to deposit inorganic particles on side walls of the plurality of pins. The total impedance to the flow of the deposition gases across the impedance disk and the extrusion die may be equal to a disk impedance of the impedance disk plus a die impedance of the extrusion die, and the disk impedance may be at least 40% of the total impedance to the flow of the deposition gases.

Abstract: An exhaust gas heating system is provided, comprising a first end face, a second end face, a plurality of honeycomb segments, and a plurality of electrically nonconductive layers. Each honeycomb segment comprises an array of intersecting walls forming channels extending axially between the first end face and the second end face. The intersecting walls comprise an electrically conductive material. The heater further comprises a plurality of electrically nonconductive layers arranged between adjacent segments of the honeycomb segments. The arrays of intersecting walls of the honeycomb segments are electrically isolated from each other by the nonconductive layers. The exhaust gas heating system further comprises a coil wrapped around an external surface of the heater arranged between the first end face and the second end face. The exhaust gas heating system further comprises a DC to AC converter configured to supply the coil with an AC current.

Abstract: A honeycomb extrusion die (120) includes a die body (342) including an inlet face (315) and an outlet face (341). A plurality of pins (330) extend from the die body (342), wherein the pins (330) are arranged to define primary (312P) and secondary slots (312S). Primary slots (312P) include primary slot inlets (320P) and primary slot outlets (3120) and the secondary slots (312S) include secondary slot inlets (312SI) and secondary slot outlets (312SO). Feedholes (317) extend within the die body (342), the feedholes (317) including feedhole outlets (319), wherein the feedhole outlets (319) intersect only with the primary slot inlets (320P). First surface indentation features (345) extend into side surfaces (332) of the plurality of pins (330) defining the primary slots (312P). The first surface indentation features (345) are spaced from the primary slot outlets (3120). The secondary slots (312S) are devoid of surface indentation features. Other die bodies, extruders, and methods are disclosed.
