Abstract
Additive manufacturing (AM) represents a technological advancement over traditional manufacturing methods, offering cost-effective production of high-quality, geometrically complex components for various applications. With its ability to rapidly manufacture metallic parts and a capability to better customise products due to the possible recycling of used powder materials, AM facilitates customized product development. On the other hand, the technology raises questions regarding microstructure, residual stresses, porosity and surface roughness. All these aspects need to be evaluated to achieve the quality of the end products. This paper reviews the corrosion behaviour of AM-produced metallic materials, examining how various factors, including porosity, microstructure, melt-pool boundaries, residual stresses, and surface roughness, influence the end-product quality.
