Patent KR-19990077673-A (KR)
IPC: F01N3/20
Filed: 1999-03-08
Abstract: A component (1) consists of an electrically conductive ceramic, in particular, a filter element, which is penetrable by a flow through its pores, and is provided with contact regions for attachment of electrodes. An electrically conductive metal is infiltrated into the contact regions (10, 11, 12, 13). An Independent claim is also included for a method for producing contact regions by infiltrating an electrically conductive metal into these contact regions. Preferred Features: The ceramic consists of a metal and ceramic compound, whose metal constituent is the same as the infiltrated metal. The ceramic of the contact layers is the same as the material of the main body of the component. The contact layers have finer bores than the main body of the component. The contact layers can be at least partially pressed into the main body of the component. Component consists of a main body (2) and a connector body (3) joined to one another. Both have the same ceramic as a basic material. The two bodies are joined by active soldering, high temperature soldering or diffusion welding. Alternatively they are joined by means of an electrically conductive connector layer. The metal infiltrated into the connector layer is partially also infiltrated into the main body of the component. For infiltration the metal is heated at least up to its melting point. Infiltration takes place in vacuum or under a protective gas. For infiltration a mixture is used in which the metal content is above the stoichiometric ratio, so that at the reaction temperature only a part of it is converted into an electrically conductive ceramic component. The connector bodies are attached to the ends of the main body (2) of the component.
