Lubricant compositions are made containing, as a metal protectant additive, an overbased amorphous alkaline earth metal salt of fatty acid. The additive is added in either a liquid or powdered form to the base oil in the composition. The overbased additive in the lubricating composition serves as a metal protectant to provide detergency, friction~modifying and acid-neutralizing properties to the compositions.
Cette invention concerne des compositions lubrifiantes contenant, en tant qu'additif de protection du métal, un sel de métal alcalino-terreux amorphe hyperbasique d'un acide gras. L'additif est ajouté à la composition soit sous forme liquide, soit sous forme de poudre. L'additif hyperbasique de la composition lubrifiante fait office d'agent protecteur de métal et confère aux compositions des prorpiétés détergentes, de modification de friction et de neutralisation des acides.
