Abstract

The aim of this work was to check if the development of laser cleaning could be suitable for complementary surface modifications of aluminium alloys before bonding. Therefore, the effects of laser treatment parameters on the induced changes of the surface composition of aluminium alloys were studied. A Q-switched Nd:YAG laser with pulse duration 10 ns, 1064 nm wavelength and 8 ns, 355 nm was used. For the in-depth surface analysis of the treated specimens, X-Ray Photoelectron Spectroscopy (XPS) in combination with Argon ion sputtering as was used. It was demonstrated by the surface analysis measurements that the remaining lubricants as well as the native oxide were removed by the applied laser treatments. This removal was resulted even though at the lowest examined laser fluence (0.8 J cm^-2). It was also clear that thermal oxidation took place, which caused a significant increase of the oxide thickness and a magnesium enrichment at the outer part of the oxide. In the range of laser fluences which was examined (0.8 – 1.4 J cm^-2), the thickness of the oxide and the magnesium enrichment were increasing by the increase of the laser energy. Nevertheless, the magnesium enrichment does not lead to a continuous and brittle layer of MgO but to a "micrograin" texture of the surface which is probably not detrimental to adhesion.
