Permeability Study of Austenitic Stainless Steel Surfaces Produced by Selective Laser Melting (open access)

Permeability Study of Austenitic Stainless Steel Surfaces Produced by Selective Laser Melting

In this article, permeability properties and surface roughness of stainless steel (SS316L) surfaces were evaluated through experimentation with three different laser scanning patterns (chessboard, meander, and stripe), and different sloping angles between the fabricated surface and the laser beam incident on the process. Results showed that for each scanning pattern, the roughness decreased as the sloping angle increased consistently in all experimental trials.

Corrosion Behavior of Selectively Laser Melted CoCrFeMnNi High Entropy Alloy (open access)

Corrosion Behavior of Selectively Laser Melted CoCrFeMnNi High Entropy Alloy

The article focuses on a study that widens the toolbox to manufacture HEAs with exceptional corrosion resistance by additive manufacturing. CoCrFeMnNi high entropy alloys (HEAs) were additively manufactured (AM) by laser powder bed fusion and their corrosion resistance in 3.5 wt% NaCl solution was studied by potentiodynamic polarization and electrochemical impedance spectroscopy tests. A systematic study of AM CoCrFeMnNi HEAs’ porosity under a wide range of laser processing parameters was conducted and a processing map was constructed to identify the optimal laser processing window for CoCrFeMnNi HEAs.
