摘　　要：采用四球机、高频往复试验机(HFRR),考察了加入清净剂高碱值硫化烷基酚钙(T115B)前后油品抗磨性能的变化;并采用SEM和EDS分析了摩擦副表面的形貌和元素分布情况。结果表明,高碱值硫化烷基酚钙有助于增加油品的润滑性能,并且随着加入量的增加,抗磨性能逐渐增加;高碱值硫化烷基酚钙中的S元素与金属表面发生化学反应,生成了金属硫化物,从而提高了油品的抗磨性能。By using four-ball tester, high frequency reciprocating rig method, the effect of overbased sulfurized calcium alkyl phenolate on the anti-wear performance of base oil was investigated, the microstructure and element distributing of the fiction surface were analysed with SEM and EDS. It is found that overbased sulfurized calcium alkyl phenolate can increase the lubrication performance of base oil, the anti-wear performance of base oil is improved with the increase of overbased sulfurized calcium alkyl phenolate. The chemical reaction takes place between S element in overbased sulfurized calcium alkyl phenolate and fiction suface, and composes a metallic Sulfide which improves the anti-wear performance of base oil.
