Enhancing Surface Properties of AM AlSi10Mg Components: A Study on Shot Peening and Silver Shell-Copper Core Coating

Abstract:

Additive manufacturing (AM), notably Laser Powder Bed Fusion (PBF-LB), has transformed metal component production, including the widely used AlSi10Mg alloy. However, optimizing surface properties for longevity remains challenging. Shot peening enhances mechanical properties, while silver shell-copper core (SSCC) coatings provide corrosion resistance and conductivity. This study investigates their combined effects on AlSi10Mg specimens, analyzing various shot media types' impact on surface roughness, coating thickness, and fatigue strength. Insights gleaned contribute to advancing surface treatment methodologies for AM components.
