Enhancement of electrical conductivity and corrosion resistance by gold-nickel coating of additively manufactured AlSi10Mg alloy

On the current research progress of metallic materials fabricated by laser powder bed fusion process: a review

“…Fig. 5(a) shows round pores with varying sizes in the AlSiMg alloy [117]. Similar round pores of various sizes are formed in 316 L stainless steel [115].…”

“…Two phenomena contribute to the initiation of hot cracks: solid deformation and insufficient convection in the liquid region caused by a large temperature gradient during solidification [137]. Owing AlSi10Mg [117] and (b) 316L stainless steel [115] and surface porosity in (ced) AlSi10Mg alloy [118]. to the rapid heating of the upper surface by the laser beam and relatively slow heat conduction, a steep temperature gradient can be generated.…”

“…5 e SEM images showing the internal and surface porosity in different materials during LPBF. Internal porosity in (a)AlSi10Mg[117] and (b) 316L stainless steel[115] and surface porosity in (ced) AlSi10Mg alloy[118].…”
