Tribotechnical properties of thin-film coatings obtained by the tribomodifcation of crankshaft pins for ship diesel engines

Abstract

The tribotechnical properties of thin-film coatings obtained as a result of the tribomodification of 40Kh steel by various organic-inorganic tribotechnical materials (natural inorganic and synthetic polymers), as well as the compositions and composites created based on vermiculite are considered in the work. Comparative tribotechnical tests have made it possible to establish that the most promising materials for the tribomodification of the friction surfaces of steels are nanostructured composites based on vermiculite, which make it possible to get the minimum coefficient of friction and high wear resistance of the conjugation under the friction condition at boundary lubrication.
