Abstract

Room temperature bonding between Al alloys and steel, which can be applied for multi-materialization for car bodies, etc., is investigated. Multi-materialization is a technology that achieves higher strength and lighter weight by using different materials together, such as Al alloys and steel. However, it can be difficult to bond a combination of Al alloys and steel by welding. In this study, the surface-activated bonding (SAB) technique was applied for bonding between Al alloys and steel. As a result, it was found that by activating only the surface of the Al, which is the active metal, the oxygen ions are deprived from the remaining oxide film on the Fe surface, and the oxide formation enables bonding.
