Title
(EN) POWDER METALLURGY LUBRICANT COMPOSITION AND METHODS FOR USING SAME
(FR) COMPOSITION LUBRIFIANTE UTILISEE DANS LA METALLURGIE DES POUDRES ET SES PROCEDES DE FABRICATION
Abstract
(EN)
The present invention provides lubricant compositions for the powder metallurgical field. The lubricant compositions contain a solid phase lubricant such as graphite, molybdenum disulfide, and polytetrafluoroethylene in combination with a liquid phase lubricant that is a binder for the solid phase lubricant. The binder can be chosen from various classes of compounds including polyethylene glycols, polyethylene glycol esters, partial esters of C3-6 polyhydric alcohols, polyvinyl esters, and polyvinyl pyrrolidones. The binder is solubilized in an organic solvent.

La présente invention concerne des compositions lubrifiantes utilisées dans le domaine de la métallurgie des poudres. Ces compositions lubrifiantes renferment un lubrifiant en phase solide tel que le graphite, le bisulfure de molybdène et le polytétrafluoroéthylène et est associé à un lubrifiant en phase liquide qui lui sert de liant. Le liant peut être choisi parmi diverses classes de composés tels que les polyéthylène-glycols, les esters de polyéthylène-glycol, les esters partiels d'alcools polyvalents en C3-6, les esters de polyvinyle et les pyrrolidones de polyvinyle. Le liant est solubilisé dans un solvant organique.
