摘要

采用水热法制备了MoO3/GO复合材料。在多功能摩擦试验机上研究了复合材料作为润滑油添加剂的性能。基于SEM和EDS测试数据，探讨了MoO3/GO在基础油中的润滑机理。结果表明，MoO3/GO复合材料作为添加剂具有优异的抗摩擦和抗磨性能。这主要是由于复合材料在磨损表面形成的润滑膜与纳米moo3的自愈能力之间的协同作用，可以有效填充和修复磨损疤痕，同时减少钢盘表面的摩擦磨损。

Preparation and tribological properties of GO supported MoO3 composite nanomaterials

The MoO3/GO composites were synthesized via a hydrothermal method. The performance of these composites as lubricating oil additives was investigated by a multifunctional friction testing machine. And the lubrication mechanism of MoO3/GO in base oil was discussed based on SEM and EDS test data. The results demonstrate that MoO3/GO composites as additives exhibit excellent anti-friction and anti-wear properties. This is mainly due to the synergistic effect between the lubricating film formed by the composite material on the wear surface and the self-healing ability of nano-MoO3, which can effectively fill and repair wear scars while reducing friction and wear on the steel disc surface.
