FIELD: polymer materials. SUBSTANCE: in a method, in which surface is doped by pressing of powdered material followed by caking, surface of press mold constituting zone of working contact with parts is covered with polyheteroarylene solution, whereupon powdered fluoroplastic-4 is loaded under pressure 35-50 MPa and then caked at 370-380 C in air. EFFECT: improved tribochemical properties of polytetrafluoroethylene with no loss of high deformation and strength characteristics. 6 ex
