用新方法合成了含 S,P,Mo 三种活性元素的油溶性有机化合物,并在四球机、Falex 试验机上作了摩擦磨损试验。结果表明:添加0.5%的该化合物到46~#汽轮机油中就能显示很好的减摩、抗极压作用,在油中、空气中均较稳定。理化性能试验表明:加入该添加剂后,基础油的理化性能均合格。用 X—射线光电子能谱(XPS)对摩擦副的表面进行了测试,初步探讨了其极压抗磨机理。 Oil-soluble organic compounds containing three active elements S, P and Mo were synthesized by a new method. The friction and wear tests were carried out on a four-ball machine and a Falex testing machine. The results show that adding 0.5% of the compound to 46 ~ # turbine oil can show good anti-friction and anti-extreme pressure effects and is stable in oil and air. Physical and chemical properties tests showed that: After adding the additive, the physical and chemical properties of the base oil are qualified. The surface of the friction pair was tested by X-ray photoelectron spectroscopy (XPS), and its extreme pressure and anti-wear mechanism was discussed.
