Analysis of Reasons for Reduction of Wear Resistance of Polymer Materials in Friction Pairs with Alloy Steel
Annotation
The wear resistance of polytetrafluoroethylene, its F4K20 composite, polyesterephyrketone, and ultrahigh-molecular polyethylene under sliding friction on carbon and alloy steels is studied experimentally. It is shown that in pairs of friction with alloy steel, a temperature regime can be created in which reactions of chemical interaction of Nickel with the polymer are activated. In the presence of polytetrafluoroethylene and its composite, the reactions are found to lead to formation of strong transfer films and an expansion of the range of workloads, and in the case of polyetherephyrketone and ultrahigh-molecular polyethylene --to a more intense heating of polymers and a reduction in the range of loads approximately in h
