FIELD: lubricant materials.

SUBSTANCE: invention relates to an addition agent to lubricant materials that comprises substances taken among the group including hydroxamates or their mixtures, diacylhydroxamates or their mixtures, β-diketonates or their mixtures, β-ketoetherates or their mixtures, hydroxamate etherates of 3d-, 4d- and 4f-metals, their substituted analogues, their mixed complexes with these metals, their mixtures and substances providing minimal abrasion in the minimal concentration, In particular, addition agent comprises substances taken among the group including nonbranched long-chain carboxylic acids, their esters, their compounds with 3d-, 4d- and 4f-metals, organic phosphates, technical grade addition agents. Also, addition agent represents substances taken among the group including carboxylates of 3d-, 4d- and 4f-metals, compounds of carboxylate hydroxylamines, compounds of esters formed by carboxylic acids and hydroxylamine with these metals, mixed complexes of carboxylic acids with abovementioned substances with these metals, in particular, mixed complexes of hydroxamic and carboxylic acids with 3d-, 4d- and 4f-metals and mixtures of indicated substances. The lubricant composition comprises a base and above described addition agents. The base is made of plastic lubricant, oil, fuel, special liquid, lubricant-cooling liquid. Invention provides improving ant-wearing and anti-scuffing properties and reducing concentrations. Proposed addition agent can be used in all branches of machine engineering for enhancing longevity, safety, economy and functional quality of machines and mechanisms.

EFFECT: improved and valuable properties of addition agent.
