Title of Paper:The influence of AA5083 surface treatments on the interface bonding performance between AA5083 and epoxy

Journal:ICCM Int. Conf. Compos. Mater.

Abstract:This paper adopts anodic oxidation, sandblasting and silane coupling agent (KH560) to deal with the AA5083 surface, studying the influence of surface treatments on the bonding performance of AA5083 aluminum with cryogenic adhesives and comparing with the samples that are only dealt with isopropyl alcohol cleaning. Using scanning electron microscopy (SEM) to observe and analyze the surface of parent metal and fracture section of bonding samples, Test the shear strength of joints, roughness and contact angles whose surfaces are dealt with sandblasting, anodic oxidation and silane coupling agent. FTIR is used to detect the chemical reaction in which Si-O-Al chemical bond is born to improve the interfacial bond strength. © 2017 International Committee on Composite Materials.
