摘要
在现役装备发动机用润滑油的基础上,进行了功能添加剂的筛选、添加剂全配方的优化设计,制备出性能优异的全配方抗磨润滑剂。采用多台模拟不同工况的磨损试验机测试了全配方润滑剂的摩擦学性能,在装备发动机上考核了润滑剂的应用效果,分析了全配方润滑剂的抗磨作用机理。结果表明采用均匀设计和复配研究方法降低了试验次数、优化了配方组成;研制的全配方抗磨润滑剂的极压性能、高温和高负荷抗磨性能分别较传统机油提高了40.8%、56.7%、82.6%,减摩润滑性能提高了45%,在改善现役装备发动机的动力性能和延长使用寿命等方面具有良好的效果;全配方抗磨润滑剂的作用机理是通过摩擦化学反应和多种功能添加剂间的复配协同效应,提升了传统军用润滑油的减摩润滑性能。
A novel full formula of anti-wear lubricant was equipped engines by selecting and optimizing some functional developed on the basis of traditional lubricant of additives. Its tribological properties were tested on several tribotesters simulating different working conditions, the application performance was investigated on equipped engines, and the anti-wear and friction-reducing mechanisms were discussed also. The results show that the experiment times are reduced and the ingredients are optimized by way of uniform design and synergistic effect research. Compared with the traditional lubricant, the extreme pressure and anti-wear properties of this lubricant under high temperature and heavy load conditions are increased by 40.8 %, 56.7 % and 82.6 %, respectively, and the friction-reducing property is improved by 45 % also. Moreover, this anti-wear lubricant can improve engine＇s power performance and prolong the service life. The mechanism is inferred that the lubrication and integrated properties of traditional lubricant are improved by tribochemical reactions and synergistic effects of the functional additives.
