the antiwear additives in polyalkylene glycol and polyurea grease at 200 °C. Results showed that they could effectively reduce the friction and wear of sliding pairs compared with the cases without these additives. Furthermore, the tribological properties of NDP and DDP were generally better than the normally used tricresyl phosphate (TCP) in PAG and molybdenum disulfide (MoS2) in polyurea grease.
萘苯基二磷酸酯:在200°C下,聚萘撑二醇和聚脲油脂中的1-萘基磷酸二萘酯(NDP)和1,5-二羟基萘双(磷酸二苯酯)(DDP)被用作抗磨添加剂。结果表明,与没有这些添加剂的情况相比,它们可以有效地减少滑动副的摩擦和磨损。此外,NDP和DDP的摩擦学性能通常优于PAG中通常使用的磷酸三甲苯酯(TCP)和聚脲润滑脂中的二硫化钼(MoS 2)。由Fe(OH)O,Fe 3 O 4,FePO 4组成的边界润滑膜形成在磨损表面上,从而具有出色的减摩和抗磨性能。
