A solid state bonding method between ceramics and metals using superplastic ceramics as interlayer-materials has been developed. Polycrystalline Al_2O_3 was used as ceramics parts to be bonded; or Ti-6Al-4V as metals parts, and 3Y-TZP, 3Y-5A, 3Y-10A, 3Y-20A, 3Y-40A, 3Y-60A as superplastic ceramic interlayer-materials. The superplastic flow of the inserted ceramic, that can arise at temperatures of about half of its melting point with low applied stresses, was utilized for the bonding process. The bonding experiments were carried out with interlayer thickness and different interlayer materials as bonding variables, and their appropriate bonding variables were discussed. A joined-material having a good bonded state was obtained for Al_2O_3/Ti-6Al-4V by using 3Y-20A, 3Y-40A superplastic ceramic as interlayer-materials.
