Assessment of tribological performance of polytetrafluoroethylene (PTFE) reservoirs embedded into two metallurgical coatings [copper-aluminium (Cu-Al) alloy and molybdenum] and arranged in three different patterns was the main aim of studies reported in this paper. PTFE reservoirs were arranged in such a way that the load on the contact, at any given moment, was supported by both PTFE and hard coating. Two different contact configurations were used.
Of the two coating materials used, the Cu-Al performed better in terms of friction force magnitude. Performance of the three different shapes of PTFE reservoirs depends on both the coating material and the contact configuration.
