Aluminum-based alloys are known for their applications in most fields, due to their physicalmechanical properties and their technological capability to lend themselves to the realization of various parts, with geometrical configurations ranging from simple to complex. These parts include those working in hydrodynamic flow fields, characterised by certain degrees of destruction by erosion created by microjets and shock waves. Such parts are the propellers of motor boats, the impellers of household pumps, radiators and pumps in the cooling system of motor vehicles. As erosion causes the surface of the part to change, causing it to fail, research is currently being developed to increase service life by increasing the resistance of the structure to cavitation erosion. This is the direction of the present work, the results of which show the effect of artificial ageing treatment at 140 °C, with a holding time of 12 hours, of aluminium alloy 2017 A. Comparison with similar results obtained previously on the delivery condition and on artificial ageing at the same temperature, with holding times of one hour and 24 hours, shows that the structure obtained by the analysed heat treatment regime is a variant for increasing the service life to cavitational stresses.
