Formation of boundary lubricating films in the presence of complexing additives

Abstract

The formation of boundary lubricating films on the surface of steel during friction in the presence of substances forming complex compounds with iron — dipyridyl, o-phenanthroline, 8-hydroxyquinoline, and ethylenediaminetetraacetic acid, is considered. Boundary layers formed in the presence of complexones increase the antifriction properties of the lubricant at low loads. It has been established that surface films are formed predominantly from base oil molecules.
