Research progress on corrosion behavior of additive manufactured alloys

摘要

Additive manufacturing (AM) techniques including powder bed fusion (PBF) and direct energ y deposition (DED) have been widely employed to fabricate l arge complex alloy components. Due to the special processing characteristics such as high cooling rate and multiple thermal cycle s, the additive manufactured alloys possess unique microstructure s and corrosion behavior s. In this presentation, we share the research progress on corrosion behavior and mechanism of additive manufactured stainless steel, high-entropy alloy, aluminium alloy and magnesium alloy in our laboratory. It is hoped these results can help to promote the industrial applications of the additive manufactured alloys.
