英文摘要: A series of chromium-containing carbon films are deposited on 316L stainless steel (SS316L) as bipolar plates for proton exchange membrane fuel cells (PEMFCs) by pulsed bias arc ion plating (PBAIP). The film characterizations are evaluated by X-ray photoelectron spectroscopy (XPS) and X-ray diffractometry (XRD). Interfacial contact resistance (ICR) between the coated SS316L samples and carbon paper is measured. Potentiodynamic and potentiostatic tests in the simulated corrosive circumstance of PEMFC are conducted to evaluate the corrosion resistance of the coated SS316L samples. The results indicate the films are primarily composed of pure carbon atoms with amorphous structure, including sp(3) and sp(2) carbon atoms. The contents of sp(3) and sp(2) carbon atom are remarkably influenced by the doping chromium. ICR and corrosion resistance of the coated SS316L sample are greatly improved owing to the surface film. The lowest ICR between the coated SS316L sample and carbon paper is only 2.8 m Omega cm(2) at the compaction force of 120 N cm(-2). The ICR has a close relationship with the contents of sp(3) and sp(2) carbon atom, and the lowest ICR is obtained for the Cr(0.23)C(0.77) film with the lowest sp(3) carbon atom content and highest sp(2) carbon atom content. The SS316L sample with Cr(0.23)C(0.77) film also exhibits the best corrosion resistance. Finally, the variations of ICR and surface morphology of the coated sample before and after corrosion testing are discussed.
