Résumé :

The improved performance and duration of an impregnated tool for the mineral drilling requires thoroughunderstanding of the mechanisms involved in the consolidation of powder mixtures in the liquid phasesintering cycle (FPL). The elements used for the manufacture of the active parts of these tools are usuallymade from mixtures of loose powders based on WC/W–Ni. The spontaneous infiltration process is themost appropriate method offers a big possibility of shapes due to molding. It lets to have considerabledensity of the metal matrix composite (MMC) constituting the active head and increase its resistance toerosion and abrasion. This work consists to develop a metal matrix composite which can constitute theactive part of a drilling tool impregnated by the infiltration of industrial process SILP (Sintering byInfiltration of an appropriate mixture of Loose Powders). The mixture of loose powders (WC/W2C–W–Ni)is infiltrated under hydrogen by a manganese bronze (Cu–30Mn–3P) and then characterized by DTA,optical microscopy, SEM coupled with EDS, HRA hardness and micro-hardness Hv0.1.
