Abstract Polymers are used routinely for equipment and infrastructure in hydrogen vehicle refueling stations, but significant gaps remain in understanding their hydrogen compatibility. The tribological properties of these materials in a high-pressure hydrogen environment is important in preventing component failure and the need for frequent replacement. We present in situ tribological studies on model rubbers, which include common fillers and plasticizer, using an in situ tribometer developed previously. Results suggest a clear, yet complicated, combined effect of the high-pressure hydrogen and the additives on the tribological performance of the chosen materials, as compared to matching experiments performed in ambient air. We find that the additives improved wear resistance in EPDM but deteriorated that in NBR due to disparate additive-polymer interactions.

掺入各种填料和/或增塑剂的橡胶材料在高压氢气中的原位摩擦磨损行为

摘要 聚合物通常用于氢汽车加气站的设备和基础设施，但在理解它们的氢兼容性方面仍存在重大差距。这些材料在高压氢气环境中的摩擦学特性对于防止组件故障和频繁更换的需要非常重要。我们使用先前开发的原位摩擦计对模型橡胶进行原位摩擦学研究，其中包括常见的填料和增塑剂。结果表明，与在环境空气中进行的匹配实验相比，高压氢气和添加剂对所选材料的摩擦学性能有明显但复杂的综合影响。
