Abstract
This paper reviews the results of a comprehensive investigation made at the author’s laboratories to determine those factors responsible for promoting the integrity and long-term durability of metal/polymer bonds used in the fabrication of aircraft and aerospace structures. Using a multidisciplinary approach and a variety of surface analytical techniques, such as extended resolution scanning electron microscopy (XSEM), X-ray photoelectron spectroscopy (XPS), ellipsometry, and a new technique we call surface behavior diagrams (SBD), we have evolved several important concepts. First, we have determined that the initial integrity of metal/polymer bonds used for structural applications depends critically upon the morphology of the surface oxide on the metal. In the case of the metals studied, Al and Ti, we have observed that certain etching or anodization pretreatment processes produce oxide films on the metal surfaces which, because of their porosity and microscopic roughness, mechanically interlock with the polymer forming much stronger bonds than if the surface were smooth.
