Conclusions
-
1.
It was shown that perfluorinated monocarboxylic acids are effective additives for preventing the spread of lubricating oils.
-
2.
Considering the conditions of application, the most promising additive of the recommended class is perfluoroenanthic acid in a concentration of 0.2–0.3% by weight.
-
3.
Simultaneously with regulation of the wetting, perfluoro acids substantially improve the antifriction properties of lubricating oils.
