The bond strength testing was performed with a 3-point bending test. Specimens were examined of the metal-ceramic interface and micro- structure by SEM. The experimental result finds that from the cross-section of specimens demonstrated that the fracture was located most often between metal and oxide layer. The mechanical interlocking is most major source in bonding strength. Because of larger roughness produced by sandblast, bonding strength of the airborne-particle abrasion in 4kg/cm2 is stronger than 2 kg/cm2.
