| 摘 要： | 为了有效降低低轨道原子氧辐照对黏结固体润滑涂层摩擦学性能的影响,满足航天器机械运动机构对空间润滑材料高可靠、长寿命的要求,在MoS_2/酚醛环氧树脂涂层中添加六甲基二硅胺烷修饰的SiO_2,制备了复合涂层,并用原子氧地面模拟装置进行辐照.分别采用X射线光电子能谱(XPS)、CSM摩擦磨损试验及扫描电子显微镜(SEM)分析了涂层原子氧辐照前后的化学组成、摩擦磨损性能及磨痕形貌.结果表明:添加SiO_2在一定程度上提高了MoS_2/酚醛环氧树脂涂层的抗原子氧剥蚀和摩擦磨损性能;添加2%SiO_2的涂层在原子氧辐照前后摩擦系数最低,耐磨性能最佳;当SiO_2添加量为1%时,涂层辐照前后的耐磨寿命最长.

| Abstract: | In order to meet the requirement for high reliability and long service life of space movement mechanisms,hexameth-yldisilazane modified SiO2 was incorporated into MoS2-doped phe-nolic-epoxy resin-based bonded solid lubricating coatings to pre-pare multi-component composite coatings.The resulting compos-ite coatings were irradiated by atomic oxygen(AO) generated in a ground-based simulation system.The friction and wear behavior of the composite coatings before and after atomic oxygen irradia-tion was evaluat... |
