- 論文の詳細を見る
Bonding of alumina to SS41 mild steel was investigated by using insert materials of Cu-Ti two-layer coatings and Cu-22wt% Ti composite coating which sprayed at low atmospheric pressure, compared with Cu-22wt% Ti mixed paste and Cu-Ti two-layer foils. The mean shear strength of the joints bonded at 900℃ and 0min using Cu-Ti two-layer coatings showed 173MPa. The maximum strengths of the joints bonded using Cu-22wt% Ti composite coating and Cu-Ti two-layer foils were obtained at the bonding time of 30min, and the strength of the joints using Cu-22wt% Ti mixed paste was very low. The strengths of joints bonded after bonding time of 30min using all kind of insert materials decreased with bonding time. It was recognized that bonding strength of joints were controlled by the eutectic reaction of Ti and Cu in the inter layer and the formation of brittle metallic compound at the interface near SS41 mild steel.
