Abstract
The erosion-corrosion behaviour of a near fully dense 316L stainless steel (316L SS), with relative density higher than 99.5%, produced by selective laser melting (SLM) has been evaluated, for the first time, in a jet impingement system. Although the SLM-produced 316L SS possessed superior pitting corrosion resistance and higher hardness, unexpectedly, it has shown lower erosion-corrosion resistance than its conventionally produced commercial counterpart. This behaviour has been related to weaker repassivation ability of the SLM-produced 316L SS mainly due to the presence of the SLM process-induced pores within the specimen.
