The properties and consequently functionality of equipment made of aluminium alloys are influenced by microstructural characteristics such as phase composition and grain size distribution in their surface layer. Nowadays, many surface engineering techniques have been applied to improve the surface properties of aluminium alloys, one of them being laser surface treatment. The effect of laser surface remelting at cryogenic conditions on the local chemical compositions, microstructure and corrosion characteristics of AlSi13Mg1CuNi aluminium alloy have been presented. The beneficial effect of laser treatment on the corrosion behaviour of the cast aluminium alloy in 0.01 M sulphuric acid solution was observed.
