Comparative study of protective and anticorrosive properties of sulfonate and phenolate greases

Abstract

The work is based on the study and comparison of protective and anticorrosive properties of sulfonate and phenolate greases. Laboratory tests were carried out on steel (protective properties) and copper (anticorrosive properties) metal plates in accordance with the rules and recommendations of GOST 9.054-75 and GOST 2917-76 methods. The results showed that all tested samples of greases provide long-term protection of steel plates in seawater. The best protective properties were shown by a sample of sulfonate grease SK-25. According to the results of studies of anticorrosive properties, all tested samples can be classified as non-corrosive to non-ferrous metals.
