| 摘 要： | 在200SN中原位合成了油溶性油酸铅，并用FT-IR对其进行了表征。用四球及往复式摩擦试验机对其摩擦学性能进行了评价，结果表明：油酸铅具有良好的抗磨性能、显著的减摩性能和中中等的极压性能。为弄清其抗磨减摩机理，用SEM及XPS表征了磨斑表面，表征结果发现，摩擦学性能的改善是因油酸铅在摩擦副表面形成吸附膜和在摩擦条件下部分吸附膜发生摩擦化学反应产生了铅氧化物膜所致。

| Abstract: | Oil soluble lead oleate is synthesized in-situ in 200SN basic oil and characterized with FT-IR . Its tribological properties as friction reducing and anti-wear additives of lubricating oil are evaluated with four-ball and reciprocation tribo-tester. The results indicates that lead oleate have excellent anti-wear property, better wear-reducing efficiency and middling extreme pressure property. Wear scar surface is characterized with photoelectron spectroscopy (XPS)and scanning electron microscopy (SEM) for explaining friction reducing and anti-wear mechanism. Analytical results show that the additive could markedly improve tribological properties of 200SN basic oil by forming adsorbing film on steel-steel friction pair and part of film transforming oxidic film by means of tribochemical reaction. |
