RESEARCHES ON ELABORATION OF COMPOSITE MICROPOWDERS WITH WOLFRAM MATRIX USING MECHANICAL ALLOYING TECHNIQUE
Résumé
The purpose of this paper is to present some researches regarding the composite micropowders with wolfram matrix in mixture with copper used in the production of electrical contacts. In order to alloy the two powder, the mechanical alloying is used. The SEM micrograph of the tungsten micropowder and copper and then the SEM micrograph of the mixture WC-Cu for the different mechanical alloying time are presented.
