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.

温度对辐射强化含氟聚合物表面层机械性能的影响

摘要

本文讨论了温度对在熔点以上经 λ 辐射处理的含氟聚合物的机械性能的影响。这种强化技术对含氟聚合物-钢摩擦副的摩擦学性能的高效性的说法得到了证实。使用动态微压痕研究了加热至 400°C 时含氟聚合物薄表面层机械性能的变化。分析了材料的硬度、弹性模量、压痕总功及其弹性成分。建议在液压系统的轴向柱塞泵中应用包含辐射强化含氟聚合物部件的摩擦副，以增加无故障运行的可能性。
