PURPOSE:To absorb deformation, etc., of a ceramic caused by heat shock with metallic layer and to reduce crack by having the ceramic part and the metal part in a brake ring and making construction joining the ceramic part and the metal part of the brake ring. CONSTITUTION:An inserted part 5 to a mold of the brake ring is made of plural-layer construction of the ceramic and the metal. The ceramic is made of zirconia ceramic partially stabilized by MgO and the metal is made of copper by casting to join the both material. The casting to join is executed by charging the copper and the ceramic in a crucible and melting the copper at the prescribed temp. and cooled as they are. After that, unnecessary part of the copper is cut off to machine to the prescribed size. By this method, the service life if extended and machining can be facilitated. |
