dc.description.abstract | In this work, powders of cemented ultrafine WC-6 wt.% Co were consolidated. The
feasibility of the medium frequency electrical resistance sintering (MF-ERS) technique were studied
to prevent WC grain growth during consolidation. Porosity and hardness were measured at different
zones of the MF-ERS compacts. The compacts showed a slight inhomogeneity in their properties
across their section, but it was controlled by choosing suitable values of the processing parameters.
The optimal values for the material studied were current intensities between 7 and 8 kA and sintering
times between 600 and 800 ms. The main achievement using this consolidation method was that
sintered compacts essentially maintained the initial WC grain size. This was attained to processing
times of less than 2 s, and without the need for using protective atmospheres. | es |
