| 摘 要： | 研究了环氧树脂在干摩擦下载荷为49 N和98 N时的摩擦磨损性能及其表面化学效应,利用扫描电子显微镜、X射线光电子能谱仪和傅立叶变换红外光谱仪对环氧树脂磨损表面的形貌和官能团进行观察与分析.结果表明:在载荷49 N下环氧树脂表现出良好的耐磨性能;在载荷98 N下,环氧树脂表面磨损较严重且呈脆性剥落;环氧树脂在干摩擦过程中发生的表面化学效应主要是其分子链的断裂和氧化降解,其磨损形式主要为疲劳磨损.

| Abstract: | Friction and wear behavior and surface chemical effects of epoxy resin at 49 N and 98 N were investigated. The surface profile and functional groups of epoxy surfaces before and after were been analyzed using scanning electron microscopy, X-ray photoelectron spectroscopy and Fourier transform infrared spectrometer. It was found that epoxy exhibited favorable wear resistance at 49 N while brittle dislodgement was perceivable on the worn surface at 98 N. The surface chemical effects of epoxy during dry friction were scission of macromolecular chains and oxidative degradation, and fatigue wear was the main wear mechanism. |
