合成出4种咪唑啉硼酸酯润滑油添加剂，在四球摩擦磨损试验机和SRV微动摩擦磨损试验机上评价了4种添加剂在液体石蜡中的摩擦磨损性能，考察了其抗腐蚀性及热稳定性，并采用扫描电子显微镜和X射线光电子能谱仪观察分析钢球磨损表面形貌及其表面膜中元素的化学状态．结果表明，所合成的添加剂具有良好的抗腐蚀性和热稳定性及极压抗磨减摩性能．这归因于含MBA-2的液体石蜡在摩擦过程中发生摩擦化学反应并生成由B_2O_3、氧化铁及含氮有机物等组成的混合膜． |

A series of imidazoline borates were synthesized. Their tribological behavior as lubricating oil additives in liquid paraffin was evaluated on the Four-ball tester and SRV tester. The worn scars of the steel balls, lubricated with liquid paraffin and 2% MBA-2 ＋ liquid paraffin separately under the load 392 N, were observed with scanning electron microscope, the chemical state of some typical elements on the worn surfaces were analyzed using X-ray photoelectron spectroscopy. The anticorrosion property and thermal stability were also investigated. The imidazoline borate MBA-2 added in the liquid paraffin could greately reduce friction coefficient and minish the wear scar diameter and enhance extreme pressure formation of the tribo-film consist meanwhile it exhibited good corrosion resistance and themal stability due to the of B_2O_3, ferror oxide, organic compound containing nitrogen on the worn surface during the rubbing process. |
