Abstract The effect of adsorbed inhibitor films on the durability of aluminium adherends prepared by the Forest Products Laboratory process was determined. Dilute aqueous solutions of phosphoric acid (PA) and nitrilotris (methylene) phosphonic acid (NTMP) were used. The presence of a monolayer of NTMP resulted in a four-fold increase in bond durability over that of untreated adherends. Dilute solutions of PA were ineffective in improving bond durability. Correlated wedge tests (coupled with a fracture energy analysis), surface composition determinations using X-ray photoelectron spectroscopy, and surface examination using high resolution scanning electron microscopy suggested that a compound's effectiveness in improving bond durability depends on its ability to inhibit the conversion of aluminium oxide to hydroxide and form chemical bonds with the adhesive.
