In this study, the effect of bonding conditions on the bonding strength between Mg alloy sheet and steel sheet produced by the ultrasonic bonding was investigated. Two types of steel sheets, cold-rolled steel sheet SPCC and electrogalvanized steel sheet SECC, were used. As a result, it was found that the bonding strength varied with the bonding time, the bonding load and the type of steel sheet. Compared to the Mg/SPCC specimen, the Mg/SECC specimen exhibits higher bonding strength due to the contribution of Zn plating film. Furthermore, for Mg/SECC specimens, an increase in bonding time leads to a fracture of the bonding interface and a reduction in bond strength.
