Effect of Ball to Powder Weight Ratio on the Particle Size of WC-10%Co Nanocomposite

Ultrafine WC and Co powders were milled by high energy ball milling with different ball to powder ratios (5, 15, 25 and 35) to produce nanoparticles of WC-10Co composite. The particle size was measured by electron microscopy (SEM and TEM). The particle size analyses by TEM were in an appropriate agreement with the SEM results. The particle size was found less than 100 nm from 15 ball to powder ratio.
