Abstract

Abstract Translated from French La présente demande est relative à un procédé d'obtention par la métallurgie des poudres d'un matériau a base d'alliage d'aluminium, de lubrifiant solide et d'au moins une céramique. Ce procédé est caractérisé en ce que l'on utilise une céramique en poudre de granulométrie comprise entre 1 et 10 µm. Il trouve son application dans la confection de pièces soumises à frottement, notamment à chaud, telles que des chemises de moteurs en vue d'obtenir principalement un compromis optimum entre les valeurs du coefficient de frottement et de la résistance au grippage et à l'usure. The present application relates to a process for obtaining by powder metallurgy a material based on aluminum alloy, solid lubricant and at least one ceramic. This process is characterized in that a ceramic powder with a particle size of between 1 and 10 μm is used. It finds its application in the production of parts subject to friction, in particular hot, such as engine liners in order to obtain mainly an optimum compromise between the values of the coefficient of friction and the resistance to seizing and wear. .
