【摘要】：在改進(jìn)后四球摩擦磨損試驗機上考察載荷和電磁場強度對不同氯化石蠟(T301)含量的潤滑油的摩擦學(xué)性能的影響,使用掃描電子顯微鏡(SEM)和能譜儀(EDS)對磨損表面進(jìn)行分析,初步探討電磁場作用下的摩擦學(xué)機制。結(jié)果表明,在不同工況下,電磁場作用下鋼球的磨斑直徑和摩擦因數(shù)均小于無電磁場作用時的數(shù)值,說明電磁場有利于改善氯化石蠟的抗磨減摩性能,且電磁場強度越大,對抗磨減摩性能的改善效果越顯著;電磁場作用下鋼球表面O和Cl元素的含量比無電磁場時高,表明電磁場有利于氯化鐵膜在鋼球表面的吸附,并對摩擦副表面摩擦化學(xué)反應(yīng)膜的形成有促進(jìn)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.
