EFFECTS OF DEIONIZED WATER IMMERSION OF PREPARED ALUMINUM SURFACES ON ADHESIVE BONDABILITY

Abstract

The effects of immersion in deionized water and in tap water on the bondability of 2024 aluminum which had been surface-treated with sulfuric acid- sodium dichromate solution were compared. Substantial losses in bond strengths were experienced with aluminum that had been immersed in deionized water. Poor bonding surfaces were readily identifiable from the formation of an iridescent coating which further investigation revealed to be related to the thickness of the hydrate layer formed. Addition of certain multivalent compounds to the deionized water was found to affect the formation of the hydrate layer and subsequently to increase the bond strengths.
