Abstract

This work studied the influence of cold deformation on the microstructure evolution and corrosion behavior of selective laser melted (SLMed) 316L stainless steel in a simulated cathode environment for proton exchange membrane fuel cells (PEMFCs). Results indicated that at < 50% deformation levels, the corrosion resistance was improved with an increase in deformation level, which was attributed to the deformation twins, refining sub-grains, and the formation of stable passive films. At 70% deformation level, martensite nucleation decreased the stability of the passive film and consequently reduced the corrosion resistance.
