Abstract

Despite the already existing advantages of additively manufactured AlSi10Mg, there are still process-induced imperfections associated with the direct metal laser sintering process, such as microstructural inhomogeneity and high level of porosity. The post-printing thermal treatments have been shown to be an effective method to reduce the microstructural inhomogeneity, but unable to diminish the porosity level of the part. In this study, friction stir processing (FSP) is introduced as a practical post-printing process capable of reducing both the porosity level and microstructural inhomogeneity of the DMLS-AlSi10Mg alloy. A detailed microstructural analysis of the as-printed DMLS-AlSi10Mg alloy before and after FSP treatment utilizing optical microscopy, scanning electron microscopy, and electron backscatter diffraction was performed. To further investigate the impact of the FSP-induced microstructural modifications and porosity reduction on the corrosion performance of the alloy, anodic polarization testing was conducted on both as-printed and FSPed DMLS-AlSi10Mg alloy.
