Description
Preferential thermal nitridation was used to form a pin-hole defect free CrN/Cr2N surface on a model Ni–Cr alloy. Excellent corrosion resistance and negligible contact resistance increase was observed over a 4100 h exposure in 80 °C sulfuric acid and when used as a metallic bipolar plate in a 1000 h proton exchange membrane (PEM) fuel cell test.
