The Influence of Metal Cations of Mechanoactivated Bentonite on Tribochemical Processes in PTFE

详细

The influence of metals of a bentonite composition on the processes of frictional interaction and tribotechnical properties of PTFE as a result of their preliminary mechanoactivation was studied. It is shown that mechanical activation liberates cations from octahedral layers of layered silicate. The formation of tribo-oxidation products and the influence of metals on tribochemical reactions have been shown and substantiated by IR spectroscopy. A correlation was obtained between the composition of the cations, the products of tribo-oxidation, and the wear resistance of composites.
