It is well known that the surface preparation of the substrates prior to adhesive-bonding is a very important step for the performances and for the long-term durability of the bonded joints in hot/wet environment. Unfortunately most of the best established procedures successfully applied on metallic substrates involve solvents cleaning and chemical treatments which are not compliant to new legislations relating to health and environmental considerations (VOC limitations, RoHS and REACH European regulations). In this paper, different laser pre-treatments were evaluated on an aluminium alloy 2024T3 and compared to other new “friendly and eco-efficient” wet surface preparations.
