| Abstract Scope |
One of the main challenges associated with the additive manufacturing of metallic components and in particular Al alloys is the high surface roughness of the parts obtained in as-printed condition, which can detrimentally affect the corrosion behavior and fatigue performance of the printed component. The present study aims to improve the surface roughness of as-printed AlSi10Mg components produced by direct metal laser sintering (DMLS) through modifying the DMLS process parameters. The electrochemical properties and corrosion resistance of the obtained surfaces were investigated by performing cyclic potentiodynamic polarization and electrochemical impedance spectroscopy, and the wettability of the fabricated surfaces was evaluated by measuring the static and dynamic contact angles on each surface. A comprehensive microstructural analysis of each sample was also conducted using optical microscopy, scanning electron microscopy, X-ray diffraction analysis, and electron backscatter diffraction to reveal the correlation of the used DMLS process parameters and the obtained surface properties. |
