TESTING AND MEASURING Free Sintering of PTFE-PEEK Blend in Air Atmosphere and its Tribological and Mechanical Properties

Free sintering in air atmosphere of an innovative bearing material based on poly(tetrafluoroethylene) (PTFE) and 15 wt. % poly(etheretherketone) (PEEK) was investigated from the point of view of degradation and the final tribological and mechanical properties.

In 2017, the study by Holmer K. and Erdemir A., which focuses on the impact of friction and wear on energy consumption, economic expenditure, and CO2 emissions on a global scale, was published. It was calculated that about 20 % of the global energy consumption is associated with friction and 3 % with the replacement/reparation of sliding components. Moreover, it has been estimated that by choosing better materials and solutions, the friction energy consumption can be reduced by up to 40 % ≈ 8 % of the global consumption.
