M ANUFACTURE of composite materials has become an important issue in recent years due to their high mechanical properties that make them suitable for many applications which needs high wear resistance and high strength.In the present work, (WC-TiC-Co) with 3,6,9,12,15, and20 wt.% ZrO2 composites were prepared by mechanical milling.The mixed powders were pressed in a uniaxial press and sintered at ...
