High-energy ball milling of WC-10Co: Effect of the milling ...
A Fritsch planetary ball milling machine, Pulverisette 7 Premium line has been utilized to mix the powders. WC-Co vials and balls were employed to avoid contamination. For each milling, the ball-to-powder ratio was kept constant at 4:1 and the milling time was set at 6 h (three separated steps of 2 h effective milling each) .
