Abstract

In order to clarify the solid phase bonding mechanism of aluminum to steel, the bonding characteristics of steel/aluminum(CS/Al) and stainless steel/aluminum(SS/Al) bonding sheets were investigated. The bonding sheets were produced by hot rolling. From the results of diffusion bonding, it was found that iron oxide film was the barrier of aluminum sheet to steel sheet bonding, however, chromium oxide film and aluminum oxide film were not always the barrier of aluminum sheet to stainless steel sheet bonding. The peel strength of the bonding sheets increased with the increase of the aluminum sheet reduction and the rolling temperature. Amorphase aluminum oxide film or chromium oxide film were observed at the interface of the CS/Al and SS/Al bonding sheet. Intermetallic compound were formed in area where oxide film was not observed. Diffusion zones of iron and aluminum were not recognized at the interface of the bonding sheets.
