Additive manufacturing is an emerging technology that challenges traditional manufacturing methods. However, the corrosion behaviour of additively manufactured parts must be considered if additive techniques are to find widespread application. In this paper, we review relationships between the unique microstructures and the corresponding corrosion behaviour of several metallic alloys fabricated by selective laser melting, one of the most popular powder-bed additive technologies for metals and alloys. Common issues related to corrosion in selective laser melted parts, such as pores, molten pool boundaries, surface roughness and anisotropy, are discussed. Widely printed alloys, including Ti-based, Al-based and Fe-based alloys, are selected to illustrate these relationships, and the corrosion properties of alloys produced by selective laser melting are summarised and compared to their conventionally processed counterparts.

增材制造是一种挑战传统制造方法的新兴技术。但是，如果要广泛使用添加技术，则必须考虑添加零件的腐蚀行为。在本文中，我们回顾了通过选择性激光熔化制造的几种金属合金的独特微观结构与相应腐蚀行为之间的关系，选择性激光熔化是用于金属和合金的最流行的粉末床添加剂技术之一。讨论了与选择性激光熔化部件中的腐蚀相关的常见问题，例如孔，熔池边界，表面粗糙度和各向异性。选择了广泛印刷的合金（包括Ti基，Al基和Fe基合金）来说明这些关系，
