    摘要： A catalyst carrier body includes a honeycomb body having sheet-metal layers and an axial extent. The sheet-metal layers are at least partly structured in such a way that the honeycomb body has passages through which an exhaust gas can flow. The sheet-metal layers of the honeycomb body have end regions lying radially outwardly. A tubular jacket has an edge and an axial span shorter than the axial extent of the honeycomb body. The tubular jacket is connected to the honeycomb body in at least one axial partial-region by a joining technique. A sleeve has an axial length shorter than the axial extent of the honeycomb body and is disposed on an outer region of the honeycomb body, in the vicinity of an end surface. The sleeve has an inner shell surface connected by a joining technique to the end regions of the sheet-metal layers at the end surfaces. The honeycomb body projects beyond an edge of the tubular jacket in a projecting section surrounded by the sleeve. In this way, stresses between the honeycomb body and the tubular jacket are avoided even with high thermal loads on the catalyst carrier body. A catalytic converter having the catalyst carrier body is also provided.

    摘要： A honeycomb body is produced in which metal sheets are stacked and/or wound in a layered configuration. The metal sheets are suitably structured so as to form passages through which a fluid can flow. At least a part of the sheet layers initially comprises a laminate material with a layer of chromium-containing steel and a layer primarily formed of aluminum. The laminate is substantially homogenized by diffusion to a stratified sheet in a subsequent heat treatment. The honeycomb body is assembled with at least a part of the sheet layers provided a structure which increases the degree of elasticity of the honeycomb body and/or the pressure in relation to surface area of the contact locations prior to and in the heat treatment. The honeycomb body is fitted into a tubular casing with such a prestressing that in the heat treatment the contact locations between the sheet layers remain in contact.

    摘要： A method for applying brazing material to metal structures is used, in particular, for honeycomb bodies of exhaust gas catalytic converters. The brazing material is applied in the form of a powder and is firmly held to the metal structures through the use of an adhesive material acting as a bonding agent, binder or adhesion promoter. The adhesive material that is used to firmly hold the brazing powder assumes two different states with respect to its adhesive action during the production process of the metal structure. A first state is less adhesive and a second state is more strongly adhesive. The adhesive strength can be selected or adjusted as a function of external conditions, especially temperature. Therefore, at a given time the adhesive material can be put into a state which is suitable for each production step, as a result of which the brazing material quality is increased and the production process is simplified.

    摘要翻译： 尤其是对废气催化转化器的蜂窝体使用向金属结构施加钎焊材料的方法。 钎焊材料以粉末的形式施加，并且通过使用用作粘合剂，粘合剂或粘合促进剂的粘合剂材料牢固地保持在金属结构上。 用于牢固地保持钎焊粉末的粘合剂材料在金属结构的制造过程中相对于其粘合作用呈现两种不同的状态。 第一状态粘合性较差，第二状态粘合性更强。 可以根据外部条件，特别是温度，选择或调节粘合强度。 因此，在给定的时间，粘合剂材料可以进入适合于每个生产步骤的状态，结果使钎料的质量提高并且生产过程被简化。
