The current research focused on assessing the corrosion process of a new aluminium alloy in a 3.5 wt% NaCl solution. Firstly, the aluminum samples were fabricated in different building orientations of AlSi10Mg aluminum: 0 \(^\circ\) , 45 \(^\circ\) , and 90 \(^\circ\) orientation using laser powder bed fusion additive manufacturing techniques. Moreover, the fabrication used three levels of laser power: scan speed, hatch spacing, and constant layer thickness, according to the Taguchi L9 experimental plan. Thereafter, the corrosion process of these samples was assessed in a 3.5 wt% NaCl solution using electrochemical impedance spectroscopy and potentiodynamic polarization curves besides morphological analysis. The results reveal that P2 and P3 samples with 16.67 and 12.00 J/mm3 in VED parameter are the most resistive from corrosion in the main conditions. These insights not only contribute to the optimization of aluminum alloy processing for enhanced corrosion resistance but also support sustainable development by extending the lifespan of materials in harsh environments, thereby reducing material waste and resource consumption.
