摘要

以次亚磷酸钠为还原剂，双烷氧基二硫代磷酸铵盐为修饰剂，在四氢呋喃-饱和食盐水的两相体系中合成了表面修饰的铁纳米颗粒，采用红外光谱仪、热分析仪等仪器对其进行了结构表征;在透射电子显微镜下观测所制备的铁纳米颗粒的形貌;在四球摩擦试验机上测试了其摩擦性能，并在扫描电子显微镜和能谱分析仪上对钢球表面进行了形貌观测和表层成分分析。结果表明，铁纳米颗粒在低极性有机溶剂中具有良好的分散性，并具有良好的抗磨和承载能力。磨斑的表面分析表明，铁纳米颗粒添加剂在边界润滑下形成了一层含Fe、S、P和O元素的表面膜是其具有良好摩擦学性能的主要原因。

Abstract

Dialkyldithiophosphate (DDP) capped Fe nanoparticles were synthesized in a two-phase system of tetrahydrofuran/saturated electrolyte with NaH2PO2 as reductant and DDP as modification agent.The structure and mophologies of surface modified Fe nanoparticles were characterized by FTIR

TGA and TEM. The tribological properties were investigated by four-ball test machine

and the worn surfaces of the balls were analyzed by scanning electron microscopy and EDS.The results showed that the surface modified Fe nanoparticles exhibited excellent solubility in low polar organic solvents and good anti-wear properties.SEM result of wear scar indicated that the main reason for the tribological properties was the formation of a layer of film composed of Fe

P and O element.
