【摘要】：在改进后四球摩擦磨损试验机上考察载荷和电磁场强度对不同氯化石蜡(T301)含量的润滑油的摩擦学性能的影响,使用扫描电子显微镜(SEM)和能谱仪(EDS)对磨损表面进行分析,初步探讨电磁场作用下的摩擦学机制。结果表明,在不同工况下,电磁场作用下钢球的磨斑直径和摩擦因数均小于无电磁场作用时的数值,说明电磁场有利于改善氯化石蜡的抗磨减摩性能,且电磁场强度越大,对抗磨减摩性能的改善效果越显著;电磁场作用下钢球表面O和Cl元素的含量比无电磁场时高,表明电磁场有利于氯化铁膜在钢球表面的吸附,并对摩擦副表面摩擦化学反应膜的形成有促进作用。
[Abstract]:The effects of load and electric magnetic field strength on the tribological properties of lubricating oils with different chlorinated paraffin (T301) contents were investigated in the improved four-ball friction and wear tester. The wear surface was analyzed by scanning electron microscope (SEM) and energy dispersive spectrometer (EDS), and the tribological mechanism under the action of electromagnetic field was preliminarily discussed. The results show that the wear surface is tribological under different operating conditions. The wear spot diameter and friction coefficient of steel ball under the action of electromagnetic field are smaller than those without electromagnetic field, which indicates that electromagnetic field is beneficial to improve the anti-wear and anti-friction performance of chlorinated paraffin, and the greater the electric magnetic field is. The better the anti-wear and anti-friction performance is; The contents of O and Cl on the surface of steel ball under the action of electromagnetic field are higher than those without electromagnetic field, which indicates that the electromagnetic field is favorable to the adsorption of ferric chloride film on the surface of steel ball. It can promote the formation of friction reaction film on the surface of friction pair.
