Additive manufacturing (AM) has revolutionised the production of metal components, opening up the possibility of designing and producing parts previously unattainable with traditional manufacturing techniques. Nevertheless, concerns remain regarding these AM-produced parts’ long-term durability and reliability. Several studies have shown that material degradation (corrosion) ranks among the foremost factors responsible for constraining the performance of metal parts. It is well-established that corrosion undermines the functionality of a component by deteriorating its mechanical characteristics, including ductility, fatigue resistance, as well as its physical and elastic properties. This review delves into the various corrosion-induced degradation mechanisms that affect metallic materials, particularly those fabricated using the Additive Manufacturing (AM) process. Furthermore, the review highlights the importance of proper post-processing techniques as a key factor in improving the durability and reliability of AM components, offering valuable insights for readers to strengthen their AM practices.

Abstract
Additive manufacturing (AM) has revolutionised the production of metal components, opening up the possibility of designing and producing parts previously unattainable with traditional manufacturing techniques. Nevertheless, concerns remain regarding these AM-produced parts’ long-term durability and reliability. Several studies have shown that material degradation (corrosion) ranks among the foremost factors responsible for constraining the performance of metal parts. It is well-established that corrosion undermines the functionality of a component by deteriorating its mechanical characteristics, including ductility, fatigue resistance, as well as its physical and elastic properties. This review delves into the various corrosion-induced degradation mechanisms that affect metallic materials, particularly those fabricated using the Additive Manufacturing (AM) process. Furthermore, the review highlights the importance of proper post-processing techniques as a key factor in improving the durability and reliability of AM components, offering valuable insights for readers to strengthen their AM practices.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
