【 摘 要 】

The influence of different factors (adhesion, surface hydrophobicity, etc.) on antifrictional properties of lubricant with modified metal additives was discussed. The measurings of friction coefficient (f) and friction force (Ffr) were carried out for the heterogeneous systems as oil I-20 with Al-additives modified by triamon (T), alkamon (A) and ethylhydridesiloxane according to various programs. It was established that as a number of T-underlayers, included in Al-additives with chemisorpted external layer of ethylhydridsiloxane reduces from 3 to 1 the force of friction and coefficient of friction reduce. It was discovered that the value of summand which stands for the amount of intermolecular forces in the boundary friction equation can be regulated in Al-additives by using low-molecular T-underlayer.
