Milling was carried out for 12 h at 240 rpm in tungsten carbide and stainlesssteel vials. Impurities such as Fe and Cr grew throughout the ballmilling process in stainless steel ball milling, which is shown in Figure 6. Fe 7 W 6 contaminant in the sample was discovered in XRD analysis, which is represented in Figure 6.

Ball milling is a key step in the processing of tungsten carbide parts. It ensures a good distribution of the different powders and reduces the crystallite size in the nanometer range by "mechanical alloying". The study of the influence of the rotation speed and the milling medium on the sinterability of the WCCo composite is important.
