Research Progress in Effect of Aluminum Surface Properties on Adhesively Bonded Performance

Surface physicochemical properties of aluminum alloy can be changed by different surface treatment methods, which determines the performance of adhesively bonded joints. This paper reviews the research status on the interfacial bonding strength and corrosion resistance of adhesively bonded aluminum alloys joints from the perspectives of surface roughness, surface micro-structure, surface oxide and coated chemistry properties. Then the problems and development of adhesively bonded aluminum alloys are discussed. The characterization of the aluminum surface physical and chemical properties and the relation model between the surface properties and the adhesive performance are considered to be focused directions for the further research.
