N2 - This paper describes dry reciprocating sliding tests of polymers against some metallic materials in gaseous hydrogen. The polymers tested included PTFE, PTFE composites, PVDF and UHMWPE, while the metallic counterfaces included hardened bearing steel, austenitic stainless steel and cobalt-based alloy. The sliding tests revealed that friction and wear depended on the counterface materials, and that the initial running-in wear influenced the subsequent steady state friction and wear. XPS analysis showed that friction and wear of the four fluorine containing polymers depended on the formation of metal fluoride on the metallic counterface.
