| Abstract Scope |
The advancement of additive manufacturing (AM) techniques, particularly laser powder bed fusion (LPBF) based fabrication, has enabled the production of complex aluminum alloy components with tailored properties. This study investigates fabrication and characterization of A356 alloy processed via LPBF, focusing on microstructure evolution and density optimization for improved corrosion resistance of the alloy. The influence of key deposition parameters—including laser power and scan speed on porosity distribution, grain morphology and physical defect evolution is systematically evaluated. Mechanical properties, such as hardness and tensile strength, are assessed alongside electrochemical corrosion behavior in 3.5% NaCl electrolyte. Furthermore, corrosion products are characterized using FTIR spectroscopy and scanning electron microscopy for evaluation of the degradation mechanisms. The findings provide insights into optimizing LPBF process parameters for enhanced A356 alloy performance, contributing to the broader application of AM aluminum alloys in aerospace and automotive industries. |
