对表面氮化的AISI316L不锈钢的电性能和腐蚀性能进行了评估，以评估该材料作为聚合物电解质膜燃料电池双极板的潜力。在AISI316L不锈钢渗氮前，在其表面电镀铬。选择只形成Cr2N氮化物的渗氮条件，并与CrN+Cr2N氮化物涂层的结果进行了比较。经Cr2N氮化物保护涂层处理的AISI316L不锈钢的界面接触抗力和耐腐蚀性均优于轧制前和(CrN+Cr2N)涂层的AISI316L不锈钢。
The electrical and corrosion properties of surface-nitrided AISI316L stainless steel are evaluated to assess the potential use of this material as a bipolar plate for a polymer electrolyte membrane fuel cell. Chromium is electroplated on the surface of the AISI316L stainless steel before nitridation. The nitriding condition is selected so as to form Cr2N nitride only and the result is compared with that of a CrN+Cr2N nitride coating. The stainless steels with the Cr2N nitride protective coating layer exhibit better interfacial contact resistance and corrosion resistance than the as-rolled or (CrN+Cr2N)-coated AISI316L stainless steels.
