Enhancement of electrical conductivity and corrosion resistance by silver shell‑copper core coating of additively manufactured AlSi10Mg alloy

A silver shell‑copper core coating was applied on additively manufactured (AM) AlSi10Mg alloy to improve the electrical conductivity, corrosion resistance, surface roughness and indentation hardness. Surface microstructure evolution and roughness of the AM alloy, i.e. as-built, during the subsequent processes, such as heat treatment, shot peening and AgCu coating, were comprehensively characterized using secondary electron imaging in a scanning...
