Microstructure and corrosion behavior of 316L stainless steel prepared using different additive manufacturing methods: A comparative study bringing insights into the impact of microstructure on their passivity

•AM 316 L microstructure consists of cells network with elemental enrichment at borders.•Cells border is highly corrosion resistant; limiting penetration of attack into metal.•Cells present on LMD specimens were about 10 times larger than those in SLM samples.•LMD, SLM and wrought 316 L had similar...
