The surface characteristics of an aluminium alloy treated with a commercial chromate pretreatment have been studied by SAM, EDX, and XPS. XPS indicates that chromium is present in the conversion coating as both Cr(III) and Cr(VI) species, and that ot

The residual stress (RS) in two curved plates cut from a large welded propellant tank for spacecrafts was investigated nondestructively by neutron and laboratory x-ray diffraction. Each plate had two weld beads symmetric to a central monoblock reinfo
A thermodynamic study of the adsorption of an epoxy acrylate resin used for UV-cured coatings on two different anticorrosion pretreatments on aluminium alloys relevant to aerospace industry has been undertaken. Aluminium alloy Al2219 specimens, treat
