Interdisciplinary approach to predictive modeling of structural adhesive bonding. Characterization of Ti-6Al-4V oxides and the adhesive/oxide interphase. Semi-annual report No. 88, September 1985-March 1986
Ti-6A1-4V, a high-strength, light-weight corrosion-resistant alloy, possesses many applications for structural adhesive bonding. This report covers the interaction of pretreated surfaces with heat, alkoxide primers, thin polymer films, structural epoxy, and hostile environments. The stability of the oxides at temperatures of 450 C is shown. Alkoxide primers enhance the durability of adhesively bonded aluminum. Characterization of alkoxide primers on Ti-6-4 has begun, as well as evaluation of these primers in the wedge test. Thin polymer films on polished titanium are studied by grazing-angle infrared spectroscopy. STEM, AES and XPS show the penetration of FM-300 into the porous oxide of CAA. Finally, the wedge test examines pretreatment stability in a variety of environments.
