A Comparative Tribocorrosion Study of Additive Manufactured and Wrought 316L Stainless Steel in Simulated Body Fluids

In this study, the corrosion and tribocorrosion behavior of additive manufactured (AM) 316L is investigated and compared to wrought 316L. The experiments were performed in both a 0.9 wt% NaCl solution and a simulated body fluid based on the protein albumin. The results are interpreted based on the a...

Description
Summary:In this study, the corrosion and tribocorrosion behavior of additive manufactured (AM) 316L is investigated and compared to wrought 316L. The experiments were performed in both a 0.9 wt% NaCl solution and a simulated body fluid based on the protein albumin. The results are interpreted based on the analysis of the microstructure, inherent AM porosities and surface roughness. The results confirm that the AM samples present a substandard behavior compared to the wrought materials due to the higher surface area caused by the voids inherent to the AM process.
