Hydrogen embrittlement (HE) can cause catastrophic failure of stainless steel valve and related components in hydrogen refueling stations (HRSs), reducing reliability, safety and increasing the cost. Here, in this study, the ability of chemically modified polytetrafluoroethylene (CM-PTFE) coatings on steel substrates in reducing the HE susceptibility and, the friction and wear of valve parts, are explored due to its low hydrogen (H2) permeability and excellent solid lubrication. The solid lubrication properties of CM-PTFE-coated steel samples were investigated before and after H2 charging at a pressure of 7 × 105 Pascals. After H2 charging, the samples were subjected to CHNS and X-ray diffraction (XRD) analysis to quantify the percentage of H2 absorption and its effect on crystallinity of the samples, respectively, and interesting insights were obtained from both CHNS and XRD analysis. Furthermore, the effect of H2 charging on uncoated steel discs and CM-PTFE-coated discs were thoroughly investigated by hardness measurements, tribological characterization, wear behavior analysis of discs and pins and chemical elemental mapping. All test results are harmoniously suggesting that the H2 charging indeed softened the material significantly. The developed double function CM-PTFE coatings can minimize H2 permeability and also reduce friction, and wear of the components in HRSs.
