摘要: Abstract This paper focuses on the influence of counterface materials sliding behaviour polymer in hydrogen. Polyimide (PI), polyetheretherketone (PEEK) and Polytetrafluoroethylene (PTFE) were investigated against hardened 52100 martensitic bearing steel 304 austenitic stainless with similar roughness (Ra = 0.2 μm). Results indicate that friction wear PI PEEK depend material. effect wasn't observed for PTFE composites. While tribological performance polyimide is better hydrogen, improved counterface, particularly at higher speed. Surface analyses transfer film reveal primarily related to chemical nature thermal conductivity disc materials.
