Abstract A new antiwear additive of Bisphenol AF bis(diphenyl phosphate) (BAFDP) was synthesized and characterized. The tribological behaviors of the additive for polyalkylene glycol (PAG) and polyurea grease (PG) application in steel/steel contacts were evaluated on an Optimol SRV-IV oscillating reciprocating friction and wear tester at elevated temperature. The results revealed that BAFDP could drastically reduce friction and wear of sliding pairs in both PAG and also in PG at 100 °C. The tribological properties of BAFDP are superior to the normally used zinc dialkyldithiophosphate-based additive package (ZDDP) in PAG and PG. Moreover, BAFDP as additive for PAG and PG displays relatively significant tribological properties in temperature-ramp tests by performing well at 50–300 °C, indicating the excellent high temperature friction reduction and anti-wear capacity of BAFDP. XPS results showed that boundary lubrication films composed of Fe(OH)O, Fe 3 O 4 , FePO 4 , FeF 2 , FeF 3 , compounds containing the P O bonds, nitrogen oxide, and so forth, were formed on the worn surface, which contributed to excellent friction reduction and antiwear performance.

双酚 AF 双（磷酸二苯酯）作为聚亚烷基二醇和聚脲润滑脂中的抗磨添加剂显着改善润滑的摩擦学特性

摘要 合成并表征了一种新型双酚AF双(磷酸二苯酯)抗磨剂(BAFDP)。在 Optimol SRV-IV 摆动往复摩擦磨损试验机上，在高温下评估了用于聚亚烷基二醇 (PAG) 和聚脲润滑脂 (PG) 的添加剂在钢/钢接触中的摩擦学行为。结果表明，BAFDP 可以在 100°C 下显着降低 PAG 和 PG 中滑动副的摩擦和磨损。BAFDP 的摩擦学性能优于 PAG 和 PG 中常用的基于二烷基二硫代磷酸锌的添加剂包 (ZDDP)。此外，作为 PAG 和 PG 添加剂的 BAFDP 通过在 50-300°C 下表现良好，在温度斜坡测试中显示出相对显着的摩擦学特性，表明 BAFDP 具有优异的高温减摩和抗磨能力。XPS结果表明，磨损表面形成了由Fe(OH)O、Fe 3 O 4 、FePO 4 、FeF 2 、FeF 3 、含PO键的化合物、氮氧化物等组成的边界润滑膜，使有助于出色的减摩和抗磨性能。
