Abstract
The creation principle and tribotechnical tests of a sheet metal-fluoroplastic material on a steel substrate are featured in the work. An optimal composition of its working layer and the procedure for doping the surface of an inversed steel pair have been selected. Tests have demonstrated that the developed material can outperform domestic commercial analogues. For instance, when the composition of new material layer is: 20_25vol. % copper alloys, 50_55%vol. % F-4 and vol. % Pb, pV factor for 1000 h continuous operation under dry friction conditions in contact with diffusion-borated steel 45 (admissible wear 200 mm) is as great as 2 MPa×1 m/s.
