摘要
合成了一种含硼杂环化合物,采用四球及环块摩擦试验机研究了其在菜籽油中的摩擦学性能,并考察了其抗腐蚀性能、氧化安定性和热稳定性。结果表明:含硼杂环化合物使菜籽油基础油的抗磨性能和承载能力都得到明显提高,减摩性能也有所改善;该添加剂还具有良好的抗腐蚀性能、优良的氧化安定性和热稳定性。采用X-射线光电子能谱分析了摩擦表面的元素化学状态,结果表明:氮和硼元素以吸附的形式存在于摩擦表面,而硫则与金属表面反应生成了含硫酸盐和FeS2的反应膜。吸附膜与反应膜的共同作用提高了基础油的减摩抗磨性能及承载能力。
A heterocyclic derivative containing boron was synthesized.Its tribological performance when added to rapeseed oil was evaluated on a four-ball tester and a ring-on-block machine.The anticorrosive properties,oxidation stability and thermal stability of the novel additive were also examined.Results indicate that compared with the rapeseed oil the wear resistance and load-carrying capacities of the oil with novel additive are improved,and the friction coefficient is decreased.The additive has good anticorrosi...
