Abstract

La présente invention concerne un nouveau procédé de production d'une poudre économique permettant de fabriquer des paliers hautes performances. Des poudres améliorées et des parties frittées améliorées (des paliers, par exemple) sont également présentées. Les poudres selon la présente invention sont formées par le mélange de poudre de fer avec de la poudre fine d'oxyde de cuivre et de la poudre d'étain élémentaire. Les poudres mélangées sont ensuite traitées thermiquement dans une atmosphère réductrice pour former un pain fritté qui est broyé sous forme de poudre.
