摘　　要：采用高频往复试验机和球柱润滑性评定仪分别考察了环烷酸在喷气燃料中的摩擦学性能,利用EDS能谱对磨斑表面微观形貌及组成进行了扫描分析,并探讨了环烷酸的润滑机理。试验结果表明:环烷酸能有效改善喷气燃料和柴油的润滑性能;环烷酸抗磨剂添加量为80μg/g以上时,既可满足喷气燃料对润滑性的要求,又能兼顾用做柴油时对燃料润滑性的要求。Tri-bological behaviors of naphthenic acids as the anti-wear additive in jet fuel were evaluated on the high frequen-cy reciprocating rig （HFRR） and the ball-on-cylinder lubricity evaluator （BOCLE）. The worn steel surface and its components were analyzed by energy dispersive spectroscopy （EDS）. The lubricating mechanism of naphthenic acids was also discussed. It was found that naphthenic acid was effective to improve lubricity of jet fuel and diesel. While dealing with naphthenic acid at concentration above 80μg/g, the lubricity requirement of diesel and jet fuel was also satisfied.
