Abstract
L'invention concerne un procédé de renforcement de matériaux particulaires sous forme d'articles présentant des combinaisons de propriétés ne pouvant pas être obtenues au moyen de procédés de frittage en phase liquide. Lesdits matériaux particulaires sont composés de particules de noyau revêtues individuellement de couches d'un composé métallique présentant une ténacité supérieure à celle du noyau, tel que WC ou TaC. Lesdites particules revêtues contiennent une couche extérieure composée de métal tel que Co ou Ni. Les particules pourvues du revêtement sont comprimées de manière à former un article et ledit article est densifié à des pressions et températures auxquelles la pleine densité est obtenue sans dégradation du matériau formant les particules de noyau.
