在这项研究中，还原氧化石墨烯（RGO）层是在沉积钛基体或Ti-29Nb-1 3Ta-4.6Zr（TNTZ）合金基体的3-氨基丙基三乙氧基硅烷（APTES）改性表面的自组装单层（SAM）上制备的。通过SEM和AFM测量表面形貌。研究了 AFM 纳米级摩擦学行为和 UMT-2 微观级摩擦学行为，并与钛基体、APTES SAM 和 GO-APTES 纳米层进行了比较。 XPS、水接触角（WCA）和椭圆光度测试作为辅助方法来讨论摩擦学机制。在纳米级和微米级摩擦学测试中，所制备的薄膜具有显着的摩擦学性能。在我们设计的生物摩擦学测试中它也显示出良好的抗磨损性能。讨论了薄膜的纳米和微米摩擦学机制。 (C) 2013 Elsevier B.V. 保留所有权利。
In this study, reduced graphene oxide (RGO) layer is prepared on a self-assembled monolayer (SAM) of 3aminopropyltriethoxysilane (APTES) modified surface of deposited Ti substrates or Ti-29Nb-1 3Ta-4.6Zr (TNTZ) alloy substrate. The surface morphology was measured by SEM and AFM. Tribological behaviors in nano scale by AFM and in micro scale by UMT-2 were investigated and compared with titanium substrate, APTES SAM and GO-APTES nanolayer. XPS, water contact angle (WCA) and ellipsometry tests were carried out as assistant methods to discuss the tribological mechanisms. In both nano and micro scale tribological tests, the prepared film holds remarkable tribological properties. It also shows good anti-wear performance in our designed bio-tribological test. Nano and micro tribological mechanisms of the film are discussed. (C) 2013 Elsevier B.V. All rights reserved.
