The paper presents experimental research regarding the wear behavior of some composite materials based on Cu/Cr and Cu/Cr/W prepared by Powder Metallurgy (PM) route. Because of low solubility between Cu and Cr is very difficult to elaborate these types of materials by classical technologies and because of that, in this research was used Mechanical Alloying (MA) technique to prepare Cu/Cr materials. In order to obtain good refractory was introduced 5% of W in the mass of materials. There were made studies regarding the wear behavior of these materials function the Cr content.
