EXPERIMENTAL RESEARCH REGARDING THE PRODUCTION OF CUTTING TOOLS THROUGH PIM TECHNOLOGY

Valeriu Sebastian CORA, Ioan VIDA–SIMITI, Liviu BRÂNDUŞAN

Abstract


In the following experimental research studies the characteristics of the materials produced through powder injection moulding for cutting tools. The material utilized is a homogenous powder mix of WC powder and 6wt% Co.  The injected parts were debinded in solvent vapor at a temperature of 75 °C for 8 hours and thermal debinded at a temperature of 70 °C for 8 hours. After debinding the samples were sintered in vacuum (10 -4Torr). The parts had contractions of 19% and a density of 97%. The material has a homogenous structure, with low porosity with no discontinuous WC particle growth.

Key words: powder injection molding, cutting tools, tungsten carbide
