On the enhanced corrosion resistance of a selective laser melted austenitic stainless steel
Qi Chao,Victor Cruz,Sebastian Thomas,Nick Birbilis,Paul K. Collins,Adam Taylor,Peter Hodgson,Daniel Fabijanic +7 more
TL;DR: In this paper, it was elucidated that an austenitic stainless steel (type 316L) when manufactured through selective laser melting was able to be produced without MnS inclusions and hence with no accompanying Cr-depletion in the vicinity of MnS, resulting in superior corrosion resistance relative to wrought form.

Corrosion behavior of TiN coated type 316 stainless steel in simulated PEMFC environments
TL;DR: In this paper, the corrosion behavior of TiN coated type 316 stainless steel (SS) was investigated in simulated proton exchange membrane fuel cell environments, i.e. 0.01 M HCl + 0.1 M Na2SO4 solutions bubbled with pure oxygen and hydrogen gases, respectively, by using electrochemical measurement techniques.

TL;DR: In this paper, the effect of different surface passivative processes on the in vitro corrosion resistance of 316L stainless steel wire was studied and the results showed that all of these surface treatments did not improve the corrosion resistance satisfactorily except amorphous oxidation, which was attributed to the removal of plastically deformed native air-formed oxide layer and the replacement of a newly grown, more uniform and compact one composed of nano-scale oxide particles with higher oxygen and chromium concentrations.
