Laser Induced Reaction for Prebond Surface Preparation of Aluminum Alloys
Abstract
The objective of this research is to establish the effect of the various parameters of the excimer ArF UV laser on the Al alloy surface microstructure and chemical activity and to evaluate the correlation between the macro behavior as reflected in shear and peel strength and the microstructure of failure locus of bonded joints. In this phase, elevated temperature cured structural adhesives were used. The second stage of this research (0002 of the contract) is summarized in this report. The results of this stage present the correlation between various laser parameters and the adhesive shear strength in order to achieve the maxim shear strength for the structural adhesives specified during the first stage (0001 of the contract). The effect of time interval between laser irradiation and adhesive bonding (open time) is reported.
