The corrosion of additively manufactured (AM) metallic materials, such as stainless steels (SS), is a critical factor for their qualification and reliable use. This review assesses the emerging knowledgebase of powder-based laser AM SS corrosion and environmentally assisted cracking (EAC). The origins of AM-unique material features and their hierarchal impact on corrosion and EAC are addressed relative to conventionally processed SS. The effects of starting material, heat treatment and surface finishing are substantively discussed. An assessment of the current status of AM corrosion research, scientific gaps and research needs with greatest impact for AM SS advancement and qualification is provided.

“…Tribocorrosion of SLM 316L was investigated by Stendal, et al, 97 in both 0.9 wt% NaCl and simulated body fluid (SBF) solution, and the performance compared to wrought 316L. The SLM 316L specimens showed a greater tendency to passivate and were less susceptible to metastable pitting than their wrought counterpart.…”

Corrosion of Additively Manufactured Alloys: A Review

et al. 2018

Additive manufacturing (AM), often termed 3D printing, has recently emerged as a mainstream means of producing metallic components from a variety of metallic alloys. The numerous benefits of AM include net shape manufacturing, efficient use of material, suitability to low volume production runs, and the ability to explore alloy compositions not previously accessible to conventional casting. The process of AM, which is nominally performed using laser (or electron) based local melting, has a definitive role in the resultant alloy microstructure. Herein, the corrosion of alloys prepared by AM using laser and electronbased methods, relating the corrosion performance to the microstructural features influenced by AM processing, are reviewed. Such features include unique porosity, grain structures, dislocation networks, residual stress, solute segregation, and surface roughness. Correlations between reported results and deficiencies in present understanding are highlighted.

“…The corrosion behavior of AM 316L is, however, more complex. [10] While some authors [11][12][13] observe an improvement in the corrosion behavior of AM components over conventional cast or wrought material, many others [14][15][16][17][18][19][20][21] report a degradation in those properties due to cracks, oxides, and porosity present in the microstructure [16,18,22] or inhomogeneous solute distributions and non-equilibrium microstructures formed during the AM processing. [17] In addition, the surface finish is shown to affect the corrosion rate.…”

This paper provides a systematic examination of microstructure and corrosion behavior of additively manufactured 316L stainless steel after post-processing by surface finishing, isothermal heat treating, or hot isostatic pressing. The effects of isothermal heat treatments from 500°C to 1300°C and hot isostatic press processing from 1000°C to 1200°C were correlated to the evolution of microstructure, pore morphology and volume fraction, microhardness measurements, and corrosion behavior to reveal the different post-processing temperature regimes and their corresponding characteristics. In particular, this study found that the AM 316L microstructures and properties are stable up to nearly 800°C. Higher temperatures eliminate the fine solidification structure, causing a drop in microhardness and corrosion resistance. Corrosion was primarily driven by the porosity content of the exposed surface and near-surface regions, which is unaffected by isothermal or HIP post-processing, and the corrosion was not significantly affected by recrystallization, which begins around 1050°C and is nearly complete by 1200°C. The amount of porosity was not markedly affected by isothermal post-processing, but could be significantly reduced by HIP processing.
