Microbial-Induced Corrosion of 3D-Printed Stainless Steels: A Surface Science Investigation

Stainless steel is a material manufactured for its high corrosive resistance and the first choice of in range applications. Microbial-induced corrosion can cause significant damage to metals responsible approximately 20% damage. The stainless reduced during manufacturing processes, including welding or joining methods, as connection points prevent metal from reforming passivation layer. Additive processes allow intricate designs be produced without need bolts. However, it unknown how layering method additive (AM) will affect steel’s layer and, turn, resistance. This research compares 316L using laser deposition traditionally AISI 316 determine affects material. Samples are incubated over 21-day period with Acidithiobacillus ferrooxidans (A.f) Leptospirillum ferooxidans (L.f) modified HH medium an approximate pH 1.8 kept at constant temperature 30 °C. Scanning electron microscopy Auger spectroscopy surface analysis techniques used identify any on samples. introductory AM technique. results show react acidic environments if could conjunction other materials underground pipes soils.
