Corrosion Resistance, Adhesion Strength, and Electrical Conductivity of 316L Bipolar Plates Treated with Combined Plasma Nitriding and TiN Coating
To enhance the corrosion resistance, adhesion strength, and electrical conductivity of bipolar plates for proton exchange membrane fuel cells (PEMFCs), a duplex surface treatment comprising plasma nitriding (PN) followed by arc ion plating of a TiN coating was applied to 316L stainless steel. The duplex coating exhibit...
