The Location of Adhesive Bond Failure by Using Radioactive Tracers

Abstract

A. L. ;Hall,J. R. ;PA-TR-4498(*bonded joints, failure(mechanics)), (*adhesives, failure(mechanics)), tracer studies, aluminum, surfaces, adsorption, radioactive isotopes, autoradiography*adhesive bonding, failure analysisThe adsorption of several radioactive ions on aluminum surfaces during the surface treatment of coupons for adhesive bonding was studied. These were chromium in the Forest Products Laboratory (FPL) chromic- sulfuric acid etch, and calcium, manganese and ferric ions in the rinse water. Calcium was the most strongly adsorbed ion, and manganese and ferric ions showed less than 1% monolayer coverage. Autoradiography was performed on coupons with very thin layers of adhesive remaining after tensile failure of the bonded specimens.
