In this master's thesis, we analysed the influence of Ultrasonic Impact Treatment (UIT) on the mechanical, microstructural and corrosion properties of aluminium alloy AA7075 in quenched and artificially aged conditions. We performed Vickers microhardness measurements, residual stress analyses using X-ray diffraction (XRD) and the hole-drilling method, surface roughness measurements, and electrochemical analyses (OCP, CPP). The results confirm that UIT improves surface microhardness, induces beneficial compressive residual stresses, modifies surface roughness, and significantly enhances corrosion resistance. Our findings indicate that the UIT method effectively increases the durability of aluminium components.
