PROCEDE DE FABRICATION DE PIECES EN CARBURE DE TUNGSTENE ET MATERIAU OBTENU A BASE DE FRITTAGE SPS DE CARBURE DE TUNGSTENE
The invention relates to a material obtained by SPS sintering, comprising pure tungsten carbide, characterized in that the material: - comprises at least one type of homogeneous grains of tungsten carbide, each of the grain types having a predetermined grain microstructure, - is devoid of binder, - has a strength of between 8 and 17 MPa-m1/2 and/or a hardness of between 1500 and 2700 (Vickers hardness HV). The invention also relates to a process for manufacturing a material based on pure tungsten carbide, characterized by the following steps: - using or grinding a powder exhibiting at least one type of grains of tungsten carbide to give grains having a predetermined grain size and a predetermined shape factor, - sintering using an SPS sintering process.
