REACTION JOINED CERAMIC COMPONENTS AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to the field of ceramics and relates to reaction-joined ceramic components which are used, inter alia, in tribologically and / or chemically stressed applications. The object of the present invention is to specify reaction-joined ceramic components which have a material of the joint seam which Essentially the same or approximately similar properties as the material of the components to be joined. The task is solved by reaction-assembled ceramic components, which consist of at least two components, each of which is bonded in the area of their surfaces to be joined with a dense material of the joint seam , which consists of at least 30% by volume of silicon carbide and at least 8% by volume of silicon, and at least one of the components has at least one cavity which is at most partially filled with silicon and / or a silicon alloy and which adjoins the material of the joint seam or there s All or part of the silicon in the cavity borders on the material of the joint seam.
