Tribochemical properties of the heterogeneous systems containing the surface-modified disperse aluminium

The priority measurings of friction coefficient (f) and friction force (F$_{\text{тр}}$) are carried out for the heterogeneous systems as oil И-20 with Al-additives modified by triamon (Т), alkamon and ethylhydridsiloxane according to various programs. It is reduced, with other things being equa, that introducing of triamon underlayers to Al-additives with the external chemisorpted layer of ethylhydridsiloxane lead to the decline of F$_{\text{тр}}$ and f in the system as far as reduction of number of Т-underlayer from three to one. It is discovered that the use of low-molecular Т-underlayer in Al-additives is the thin method of regulation of value of summand (from 10.8 to 13.2 Н), answerable in equation for intermolecular forces in the used tribological pair.
