摘　　要：合成了一种新型十二烷氧基硼酸钡(BaOB),采用红外,元素分析,热重,扫描电镜等对其进行表征。将其用做润滑油抗磨减摩添加剂,采用四球摩擦磨损试验机评价了其在菜子油(RO)中的摩擦学性能;结果表明:加入添加剂后,其承载能力得到明显提高,磨斑直径和摩擦系数均明显降低。SEM结果说明添加剂的磨斑直径明显小于基础油的,同时磨斑上有添加剂的沉积,从而改善了菜子油的摩擦磨损性能。Oil-soluble barium octoxyborate was synthesized.Its tribological properties as lubricating oil additive were evaluated using four-ball machine.The worn steel surface was investigated using X-ray photoelectron spectroscopy.The results indicate that the wear resistance and load-carrying capability were increased.Its friction coefficient was decreased by the addition of additive,and the friction coefficient under 588N is lower than that of 392N.The XPS analyses indicate that the tribochemical reaction are involved in the friction progress,which generates a protective film containing FeBand FeB on the worn steel surface.This contributes to improving the anti-wear and extreme pressure properties of the rapeseed oil.
