摘要
以钼酸铵和醋酸为原料合成纳米MoO3,并采用四球机考察纳米MoO3在润滑油、润滑脂中的抗磨性能。结果表明,纳米MoO3与油酸、二烷基二硫代磷酸锌在润滑油中具有良好的抗磨协同效应,在锂基润滑脂中具有良好的抗磨性能,尤其在高添加量和高负荷下作用更为明显。这表明纳米MoO3作为固体润滑剂,能够提高润滑油、润滑脂的摩擦学性能。
The MoO3 nano-particle was synthesized using ammonium molybdates and acetic acid. A four-ball machine was used to evaluate the anti-wear property of MoO3 in lubricating oils and Lithium-soap greases. The results indicate that MoO3 has good anti-wear synergisms with oleic acid and a zinc dialkyldithiophosphate （ZnDDP）, and has good anti-wear properties in a Lithium-soap grease, especially under the high concentrations and loads. As solid lubricating additive, MoO3 can improve the tribological performance of lubricating oils and Lithium-soap greases.
