Abstract
This article discusses the influence of temperature on the mechanical properties of a fluoropolymer treated by λ irradiation above the melting point. The statement of the high efficiency of this strengthening technology on the tribological properties of the fluoropolymer–steel friction pair is substantiated. The changes in mechanical properties in a thin surface layer of the fluoropolymer as a consequence of heating to 400°C are studied using kinetic microindentation. The material hardness, elasticity modulus, total work of indentation, and its elastic constituent are analyzed. It is proposed to apply friction pairs containing radiationally strengthened fluoropolymer parts in the axial piston pumps of hydraulic systems in order to increase the probability of faultless operation.
