Definitions

  • the present invention relates to a housing, in particular a jacket tube, for a honeycomb body and to the production of a honeycomb body with such a housing.
  • Honeycomb bodies of this type are preferably used as catalyst carrier bodies in exhaust systems of internal combustion engines, in particular in motor vehicles.
  • WO 99/37896 describes a method for producing a honeycomb body which is surrounded by a tubular casing.
  • the honeycomb body and the casing tube have different thermal expansion behavior due to their different material properties and due to different temperatures during operation.
  • the aim is therefore to avoid a rigid connection between the honeycomb body and the casing tube on at least one end region of the honeycomb body or in any case in certain partial regions.
  • the coated honeycomb body described in WO 99/37896 is designed with a sleeve which, despite manufacturing tolerances of the jacket tube and the honeycomb body, is intended to ensure that direct soldered connections between the honeycomb body and the jacket tube are avoided in the at least one end region of the honeycomb body.
  • the use of a sleeve leads to a significant reduction in thermal stresses between the casing tube and the honeycomb body, but causes a higher manufacturing outlay.
  • Means which prevent a connection of metal surfaces during high-temperature machining (such as, for example, sintering or soldering). These usually contain fine ceramic particles, a binder, and a proportion of diluent and solvent. The binder so- like the diluent and the solvent are volatile even at relatively low temperatures.
  • the connection between the casing tube and the housing is preferably formed in a vacuum, the tendency of these agents to volatilize making it difficult to maintain the vacuum and the system can be contaminated by volatile constituents.
  • the present invention is based on the objects of specifying a housing for a honeycomb body, which selectively enables technical connections to compensate for the different expansion behavior of the honeycomb body and casing pipe and ensures permanent fixation of the honeycomb body, for example in an exhaust gas system, and the specification of a method for the production a catalyst carrier body with such a housing.
  • the housing according to the invention for a honeycomb body comprises a tubular casing with an inner wall, the tubular casing having a passivation layer in at least one section of the inner wall in order to specifically prevent a technical connection with the honeycomb body.
  • the passivation layer is thermally very stable and prevents any joining of the metal surfaces in contact with one another.
  • the section on which the passivation layer is attached is located at the location of the casing tube, at which, during later operation of the catalyst carrier body, there is a relative movement between the honeycomb body and the casing tube is desired to prevent thermal stresses. This is preferably the end region in which the hot exhaust gas hits the catalyst carrier body. Areas further inside can also be kept free of technical connections.
  • the passivation layer is designed as a ceramic application layer, in particular with aluminum oxide.
  • the ceramic particles are particularly attractive to one another and have very good thermodynamic stability.
  • a ceramic layer made of titanium oxide or magnesium oxide is also possible.
  • the passivation layer is designed as a circumferential strip. This ensures that in this section, solder connections between the casing pipe over the entire circumference of the casing pipe and honeycomb bodies are avoided and different expansion behavior can be compensated for.
  • the housing has an oval or elliptical shape
  • An oval shape of the housing is required, for example, if the installation of a catalyst carrier body with the housing is tied to certain spatial conditions of an exhaust system.
  • the passivation layer has an axial length of 5 mm to 50 mm. This enables the housing to be precisely matched to the respective application. If, for example, the housing is arranged relatively close to a combustion engine or if the thermal expansion behavior of the honeycomb body and the casing tube diverge very strongly, the passivation layer is made with a greater axial length.
  • the passivation layer has a thickness of 0.03 mm to 0.12 mm. This enables in particular the balancing of manufacturing tolerances of the honeycomb body and the casing tube in the assembled state.
  • an adhesive layer is arranged between the casing tube and the ceramic layer. This is particularly advantageous when the ceramic layer is exposed to a high dynamic load.
  • the adhesive layer enables the ceramic layer to be permanently bonded to the metallic surface of the tubular casing.
  • the passivation layer prevents the formation of soldered connections between the honeycomb body and the tubular casing.
  • the honeycomb body consists, for example, of a multiplicity of sheet metal layers produced by winding and / or stacking, then a solder connection of adjacent ends of the sheet metal layers to one another can be ensured by the solder arranged on the passivation layer.
  • a catalyst carrier body is designed with a housing according to the invention and a honeycomb body arranged therein.
  • the honeycomb body is made of sheet metal layers which are at least partially structured in such a way that the honeycomb body has channels through which an exhaust gas can flow.
  • the jacket tube at least partially surrounds the honeycomb body and is joined to the honeycomb body in at least one axial partial region. The selective joining technology connection of honeycomb body and casing pipe ensures a long service life of the catalyst carrier body.
  • the ceramic layer near an end face of the honeycomb body.
  • radially outer end regions of the sheet metal layers of the honeycomb body rest on the ceramic layer.
  • the flutter of these radially outer end areas can thus be reduced. loading It is particularly advantageous to connect the adjacent end regions to one another by means of joining technology. This ensures a long service life even under extreme dynamic loads.
  • the honeycomb body is soldered to the jacket tube, preferably high-temperature vacuum soldered.
  • a method for producing a catalyst carrier body with a honeycomb body and a jacket tube is proposed.
  • the honeycomb body is made of sheet metal layers which are at least partially structured in such a way that the honeycomb body has channels through which an exhaust gas can flow.
  • the jacket tube has an inner wall which at least partially surrounds the honeycomb body and which is soldered to the honeycomb body in at least one axial partial region. In at least a section of the inner wall, the jacket tube has a passivation layer to specifically prevent a soldered connection to the honeycomb body.
  • the manufacturing process includes the following steps:
  • a passivation layer is then formed on the inner wall of the jacket tube in at least one section.
  • a soldered connection between the casing tube and the honeycomb body is prevented in a subsequent soldering process.
  • This section is preferably arranged near an end face of the honeycomb body in the inserted state. Then the inner wall of the jacket tube is bedded.
  • the honeycomb body is formed in a known manner by stacking and / or winding sheet metal layers, which are at least partially structured such that the honeycomb body has channels through which an exhaust gas can flow.
  • the honeycomb body is now inserted into the jacket tube. Then the solder joints are formed.
  • a catalyst carrier body can be produced which is characterized on the one hand by a permanent connection between the honeycomb body and the casing tube, but on the other hand also allows a compensation of different expansion behavior of the honeycomb body and the casing tube. No vapors or gases arise during the soldering process which impair the formation of soldered connections, particularly in a vacuum.
  • the passivation layer is generated by selective, spatially limited heating of the at least one section.
  • the section of the housing is consequently heated to a temperature and, if appropriate, also held at this temperature in order to enable diffusion processes in the material and on the inner wall of the housing.
  • ferritic materials containing aluminum and chromium which are heated to a temperature above 1100 ° C., are particularly suitable.
  • Metal particles, in particular aluminum come from the inside into the vicinity of the inner wall of the casing tube, which now react with the oxygen particles from the environment to the desired passivation layer.
  • the passivation layer can consequently be produced without an additional material.
  • an oxygen-containing gas is passed through the at least one section during the production of the passivation layer.
  • a rich supply of oxygen molecules is guaranteed on the inner wall, which in the formation of a Surface oxide layer are needed.
  • the creation of a passivation layer is very favored.
  • a noble gas in particular argon
  • the noble gas prevents the formation of the oxide layer because the noble gas does not react with the metal particles of the jacket tube and displaces the atmospheric oxygen.
  • the passivation layer by chemical treatment of the at least one section.
  • the section is treated with a chemical that leads to the formation of a surface oxide layer.
  • This process step is particularly suitable for jacket tubes that have been manufactured with very small manufacturing tolerances in relation to the honeycomb body to be accommodated. Thermal treatment without the honeycomb body and thus thermal distortion can be prevented.
  • the passivation layer is produced by applying a ceramic application layer, in particular aluminum oxide.
  • an adhesive layer is applied to the relevant section of the inner wall of the casing tube before the ceramic layer is formed. This leads to a particularly stable connection between the ceramic layer and the casing tube.
  • This adhesive layer preferably has no volatile components in order to ensure a reliable soldering process.
  • Flame spraying is characterized by a special the even distribution of the ceramic layer on the inner wall of the jacket tube, whereby pressure peaks in the jacket tube due to the adjacent metal layers are avoided.
  • an adhesive medium for producing a solder layer is applied before the soldering of the inner wall of the jacket tube, in particular also on the ceramic layer.
  • the adhesive medium has the task of fixing the solder powder at the points on the jacket tube at which a soldered connection is to be carried out during the later soldering process.
  • the adhesive medium on the ceramic layer also ensures the arrangement of solder powder in the area of the honeycomb body in which a connection to the jacket tube is undesirable. This solder layer serves to later solder adjacent sheet metal layers of the honeycomb body to one another.
  • solder powder is applied to the face of the honeycomb body on the face of the honeycomb body during or after the honeycomb body has been introduced. In this way, the end regions of the sheet metal layers near the end face are soldered to one another and the life of a catalyst carrier body produced in this way is increased.
  • the passivation layer is produced by roughening the inner wall in the at least one section. It is particularly advantageous here to roughen with the sandblasting and / or brushing manufacturing processes. Surprisingly, the resulting roughness of the inner wall prevents wetting by a solder in this section, a technical connection between the honeycomb body and the casing tube being prevented. A passivation layer that can be produced particularly inexpensively is thus specified. Further details of the catalyst carrier body according to the invention and a method for its production are explained with reference to the particularly preferred exemplary embodiments shown in the drawing.

  • the honeycomb body 4 is then connected to the casing tube 1 by joining technology in the partial region 11.
