Abstract

Micro-powder injection moulding (MIM) is the fastest growing technology within the powder metallurgy area. The reason for this growth is that it is an efficient production method. In this work, the fabrication of WC-TiC-6% was studied. The result showed that Solvent debinding + thermal debinding was efficient to dislodge binders with no influence on the carbon content of samples. It’s better to remove the binders and control the carbon content of greens at 450 and hold for 1.5 hour; During the liquid phase sintering process, with the 2 /min rate to heat up to 1430 and hole for 90min obtained the alloy and exhibited transverse rupture strength, Vickers hardness, coercivity and density are 1754MPa, HRA92.5, 14.43g•cm-3.No carbon interspersion and phase appeared.
