Abstract

The presented work deals with the study of the effect of increasing the doses of irradiation by accel-erated electrons on the sliding properties of polymer materials. Due to the influence of radiation, sur-face roughness changes occur on the surface of the experimental materials, which lead to changes in the properties of the coefficient of friction on the selected polymer materials. Three types of polymer materials PET, PTFE and PE2000C were used for the experimental research, which, due to their properties, are used for different types of sliding products. A steel ball of G40 material was used as a pressure material, which moved along a linear path on which the load was increased from 10 N to 100 N. Electron beam accelerators with the conversion of electrons to X-rays combine the advantages of a high ability to penetrate gamma photons sources and high performance of electron beam devices. The application possibilities of the device are wide due to the dual mode of operation (electron beam or X-ray beam) and a wide range of applicable doses and also dose rates.

加速电子辐照对高分子材料PET、PTFE和amp摩擦学行为变化的影响PE2000C

本文研究了增加加速电子辐照剂量对高分子材料滑动性能的影响。由于辐射的影响，实验材料表面发生表面粗糙度的变化，从而导致所选高分子材料摩擦系数的性质发生变化。实验研究使用了PET、PTFE和PE2000C三种高分子材料，由于其性能不同，用于不同类型的滑动制品。采用G40材料的钢球作为压力材料，使其沿线性路径运动，使载荷从10 N增加到100 N。电子束加速器将电子转换为x射线，结合了高穿透伽马光子源的能力和电子束器件的高性能的优点。由于双操作模式(电子束或x射线束)和广泛的适用剂量和剂量率范围，该装置的应用可能性很广。
