Abstract

Experimental studies on tribotechnical characteristics of lubricants with fullerene compositions are presented. It has been shown that a reasonable concentration of fullerene additive is represented by 0.75 g of fullerenes and 99.25 g of vegetable oleic oil as a solvent for fullerenes, as well as the further addition of this composition to 1 kg of the base oil, which amounts to 10% as expressed in the volume concentration. Results confirming that fullerene additives improve the antiwear properties of base lubricants by 26.6% are presented. Simultaneously, the range of the lubricant operation with the use of antiwear additives increases by 40.9%. Fullerene additives have no effect on the antiwelding properties of the base lubricant. The use of fullerene additives most efficiently reduces the friction coefficient (by 32.4–86%), as compared to the 20–25% decrease in wear rate. Experimental studies have shown that the line towards reducing the bulk wear rate and the friction coefficient by increasing fullerene additive concentration over 100 g/kg should be considered as inefficient.

润滑油中富勒烯存在下摩擦系统摩擦学特性的评估

摘要

提出了具有富勒烯成分的润滑剂的摩擦学特性的实验研究。已经表明，富勒烯添加剂的合理浓度由0.75 g富勒烯和99.25 g植物油油（作为富勒烯的溶剂）表示，以及将该组合物进一步添加到1 kg的基础油中。至体积浓度的10％。结果证实了富勒烯添加剂可将基础润滑剂的耐磨性提高26.6％。同时，使用抗磨添加剂的润滑剂工作范围增加了40.9％。富勒烯添加剂对基础润滑剂的抗焊接性能没有影响。使用富勒烯添加剂可以最有效地降低摩擦系数（降低32.4–86％），与磨损率降低20–25％相比。实验研究表明，通过增加富勒烯添加剂浓度超过100 g / kg来降低整体磨损率和摩擦系数的生产线应被认为是无效的。
