Abstract
Tungsten carbide is widely used in the production of cutting tools and parts with very good resistance to wear. It is well known that the properties of sintered carbides are closely related to the carbide particles size. Tungsten carbide production is a laborious process, which always includes a milling step. This article aims to study the manufacturing of tungsten carbide by carburizing tungsten trioxide using mechanical alloying (MA) method, thus concentrating the process in one step. Experimental tests were performed with a Fritch planetary mill and complete conversion of tungsten trioxide in carbide was observed after 30 h of milling. The average value of D50 for the synthetized WC is 6.73 ± 0.62 μm.
