In a method of making a gaseous emissions treatment component, a ‘green’ ceramic mix is extruded through a die to form an extrusion having cells extending along the extrusion, the cells being bounded by walls dividing adjacent cells from one another. In concert with the extruding, metal is fed through the die with the extruded mix. A length of the extrusion and associated metal is then cut off and fired to form the component.

The method for flame coating tubular elements provides for arranging a said tubular element (2) to be coated at a coating station, providing an applicator unit (3), operating in the coating station, in an inactive configuration, spaced from the tubular element (2), the applicator unit (3) carrying at least one thermoplastic powders flame applicator device (4) and being alternatively operable between the inactive configuration and an active configuration, approached radially to the tubular element (2). After having brought the applicator unit (3) towards the tubular element (2), the method provides for operating the same unit (3) in the active configuration, so as to peripherally engage the element (2) itself. The applicator device (4) is turned on, the thermoplastic powders are fed and the applicator device (4) is operated in motion around and/or along the tubular element (2) so as to flame coating it with a controlled flow of thermoplastic powders.

A gaseous emissions treatment component is made by extruding a green ceramic mix through a die to form an extrusion having a honeycomb substrate with elongate cells extending its length and with the cells bounded by walls dividing adjacent cells from one another. Molten metal for use in induction heating of the component is placed in selected cells and is solidified by cooling.

A multi-component electro-mechanical flame spray deposition system is disclosed having a first electro-mechanical feeder and a second electro-mechanical feeder, each in communication with a mixing hopper, and wherein the mixing hopper is in communication with a powder nozzle having an orifice, and a combustion torch having an orifice, wherein the orifice of the powder nozzle is in juxtaposition to the orifice of the combustion torch. A method of using the multi-component electro-mechanical flame spray deposition system is provided for depositing substrates on or to articles of manufacture.
