Abstract
(EN)
Provided are a method for inspecting lubricating oil compositions and a method for producing a lubricating oil composition, wherein even for fullerene-containing lubricating oil compositions, the wear resistance properties can be reliably reproduced using a relatively easy measurement method. In the method for inspecting lubricating oil compositions, the dynamic surface tensions (Σ) of lubricating oil compositions containing a base oil and fullerene are measured, and a lubricating oil composition is selected on the basis of a predetermined range set by a correlation between the measured values of the dynamic surface tensions (Σ) and the measured values of the wear coefficients of the lubricating oil compositions.

L'invention concerne un procédé d'inspection de compositions d'huile lubrifiante et un procédé de production d'une composition d'huile lubrifiante, les propriétés de résistance à l'usure pouvant être reproduites de manière fiable à l'aide d'une méthode de mesure relativement facile, même pour des compositions d'huile lubrifiante contenant du fullerène. Dans le procédé d'inspection de compositions d'huile lubrifiante, les tensions de surface dynamiques (Σ) de compositions d'huile lubrifiante contenant une huile de base et du fullerène sont mesurées, et une composition d'huile lubrifiante est sélectionnée sur la base d'une plage prédéterminée définie par une corrélation entre les valeurs mesurées des tensions de surface dynamiques (Σ) et les valeurs mesurées des coefficients d'usure des compositions d'huile lubrifiante.
