The laser surface melting of AA2024-T3 alloy modified a structure of surface layer resulting in cells and/or cellular dendrites of very fine microstructure. There are mainly two phases, i.e. primary solid solution and precipitated Al2Cu phase, around the cell boundaries. Some minor traces of Fe and Mn are also present. The estimated decrease of Cu content in precipitates is approximately 25%. The susceptibility to pitting corrosion of laser melted AA2024-T3 surfaces characterised by pitting potential was not improved in comparison with as-received material, mainly due to non-uniform structure at subsequent laser tracks.
