Investigation for Multi-Layer CuAl8 and Multi-Material (CuAl8-Mild Steel) Deposition via WAAM Process

Abstract

Wire arc additive manufacturing (WAAM) according to ISO/ASTM 52900:2021 is a widely known additive manufacturing process to produce a new 3D part or repair a damaged metal part. Copper-based alloy, i.e., CuAl8, is widely used to repair marine structures and to make bearing overlays due to its excellent corrosion and wear resistance properties. This paper will give an insight into the multi-layer deposition of CuAl8 at different substrate orientations. Furthermore, multi-material deposition, i.e., CuAl8 and mild steel, is investigated, which can help industries to combine the features of both materials and lead to the development of functionally graded materials.
