Title
(EN) METHOD FOR THE ASSESSMENT OF THE DISPERSING CAPACITY OF NEW OR USED LUBRICATING COMPOSITIONS AND OF ADDITIVES FOR LUBRICATING COMPOSITIONS
(FR) PROCÉDÉ D'ÉVALUATION DE LA CAPACITÉ DE DISPERSION DE NOUVELLES COMPOSITIONS LUBRIFIANTES OU DE COMPOSITIONS LUBRIFIANTES UTILISÉES ET D'ADDITIFS POUR DES COMPOSITIONS LUBRIFIANTES
Abstract
(EN)
A method for the assessment of the dispersing capacity of new and used lubricating compositions, in particular for internal combustion engines, and of additives for lubricating compositions, comprises the steps of: providing a homogeneous dispersion of at least one carbonaceous particulate in a composition to be tested, consisting of a lubricating composition or a fraction or component thereof; acquiring at least one micrographic image of a sample of said homogeneous dispersion, deposited on an observation support; calculating the lacunarity of the acquired image as a parameter representative of the degree of dispersion of the particulate in the composition.
(FR)
La présente invention concerne un procédé d'évaluation de la capacité de dispersion de nouvelles compositions lubrifiantes et de compositions lubrifiantes utilisées, en particulier pour des moteurs à combustion interne, et d'additifs pour des compositions lubrifiantes, comprenant les étapes consistant : à fournir une dispersion homogène d'au moins une particule carbonée dans une composition à tester, composée d'une composition lubrifiante ou d'une fraction ou d'un composant de celle-ci ; à acquérir au moins une image micrographique d'un échantillon de ladite dispersion homogène, déposée sur un support d'observation ; à calculer la lacunarité de l'image acquise en tant que paramètre représentant le degré de dispersion de la particule dans la composition.
