The electrochemical corrosion cells will be generated from the possible pinholes of the
promising CrN and TiN coatings in a PEMFC environment. To prevent the elution of possible
pinholes, CrN/TiN multi-coatings on SS have been considered. This study examined the
electrochemical behavior of three CrN/TiN coatings on 316L stainless steel deposited at
different CrN/TiN thickness ratios by rf-magnetron sputtering as potential bipolar plate
materials. Potentiodynamic tests of CrN/TiN-coated 316L stainless steel carried out in a 1M …
