采用多弧离子镀技术在316L衬底上成功地沉积了TiN涂层。用电化学方法研究了TiN涂层316L在0.05M H_2SO_4+2.2ppm·F-−模拟质子交换膜燃料电池环境中的腐蚀行为，并测量了质子交换膜燃料电池在恒电位极化前后的界面接触电阻。TiN涂层的316L在模拟侵蚀性PEMFC环境中表现出良好的ICR和更好的耐腐蚀性。恒电位极化后，只观察到一般的整体腐蚀。TiN涂层316L在工作电位下经恒电位极化后，表面形成稳定的钝化膜，ICR略有增加。这些结果表明，TiN涂层316L是一种用于PEMFC电堆的候选双极板材料。
TiN coating is successfully deposited on 316L by multi-arc ion plating. Corrosion behavior of TiN coated 316L is studied in 0.05 M H2SO4+ 2 ppm F−simulating proton exchange membrane fuel cell (PEMFC) environments using electrochemical method, and interfacial contact resistance (ICR) is measured before and after potentiostatic polarization at operation potential for PEMFC. The TiN coated 316L exhibits promising ICR and improved corrosion resistance in simulated aggressive PEMFC environments. Only general overall corrosion is observed after potentiostatic polarization. Stable passive film has formed on the surface of the TiN coated 316L after potentiostatic polarization at the operation potential and results in a slight increase in the ICR. These results indicate that the TiN coated 316L is a candidate bipolar plate material for PEMFC stacks.
