An article of manufacture includes a cemented carbide piece7 and a joining phase that binds the cemented carbide piece into the article. The joining phase includes inorganic particles and a matrix material. The matrix material is a metal and a metallic alloy. The melting temperature of the inorganic particles is higher than the melting temperature of the matrix material. A method includes infiltrating the space between the inorganic particles and the cemented carbide piece with a molten metal or metal alloy followed by solidification of the metal or metal alloy to form an article of manufacture.
L'invention concerne un article manufacturé qui inclut une pièce en carbure cémenté 7 et une phase de liaison qui lie la pièce en carbure cémenté dans l'article. La phase de liaison inclut des particules inorganiques et un matériau de matrice. Le matériau de matrice est un métal ou un alliage métallique. La température de fusion des particules inorganiques est supérieure à la température de fusion du matériau à matrice. Un procédé inclut l'infiltration de l'espace entre les particules inorganiques et la pièce en carbure cémenté avec un métal ou un alliage métallique fondu suivie de la solidification du métal ou de l'alliage pour former un article manufacturé.
