RESEARCHES REGARDING THE ELABORATION OF THE COMPOSITE MICROPOWDERS WITH WOLFRAM MATRIX USING MECHANICAL ALLOYING TECHNIQUE
Keywords:
Micropowders, copper, mechanically alloyed, SEM micrographAbstract
The main purpose of this paper is to presents some researches regarding the composite micropowders with wolfram matrix in mixture with copper used in production of the 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.
