JOINT PLATE OF CERAMIC AND METHOD FOR JOINING THIS JOINT PLATE TO METALLIC PLATE

PURPOSE:To enhance joint strength by continuously arranging ceramics chips, connecting and fixing the mutually connected parts with joint metal and then fixing this fixed ceramics joint plate to a metallic plate by a bolt. CONSTITUTION:A ceramics joint plate 3 is formed by zigzag arranging the ceramics chips 1 such as SiC made of a square of 20 to 30mm and applying an Ag-Cu-Ti-based active metallic paste-brazing material to the contact parts X of the respective ceramics chips 1 and arranging the ringlike joint metallic pieces 2 such as Cu, Ni, W and Mo, heating and joining them. Bolts 4 are uniformly dispersed and provided at the prescribed intervals to the installation parts of the joint metal of this joint plate 3. The intervals between the bolts 4 and the joint metal 2 are buried by the brazing material and both are heated and joined. The bolts 4 are perforated through the metallic plate and fixed by mechanical joint for clamping them by nuts. Further brazing material is applied to one part or the whole part of many joint metals 2. The applied faces are allowed to coincide with the metallic plate. This metallic plate can be tightly joined to the ceramics joint plate 3 by locally heating it with high frequency induction.
