A macroscopic composite sintered powder metal article including a first region including cemented hard particles, for example, cemented carbide. The article includes a second region including one of a metal and a metallic alloy selected from the group consisting of a steel, nickel, a nickel alloy, titanium, a titanium alloy, molybdenum, a molybdenum alloy, cobalt, a cobalt alloy, tungsten, and a tungsten alloy. The first region is metallurgically bonded to the second region, and the second region has a thickness of greater than 100 microns. A method of making a macroscopic composite sintered powder metal article is also disclosed, herein. The method includes co-press and sintering a first metal powder including hard particles and a powder binder and a second metal powder including the metal or metal alloy.

L'invention porte sur un article en métal à base de poudre frittée composite macroscopique comprenant une première région incluant des particules dures cémentées, par exemple un carbure cémenté. L'article comprend une seconde région comprenant l'un parmi un métal et un alliage métallique choisi dans le groupe constitué par un acier, le nickel, un alliage de nickel, le titane, un alliage de titane, le molybdène, un alliage de molybdène, le cobalt, un alliage de cobalt, le tungstène et un alliage de tungstène. La première région est liée métallurgiquement à la seconde région, et la seconde région a une épaisseur de plus de 100 micromètres. L'invention porte sur un procédé de fabrication d'un article en métal à base de poudre frittée composite macroscopique. Le procédé comprend la co-compression et le frittage d'une première poudre métallique comprenant des particules dures et un liant pulvérulent et une seconde poudre métallique comprenant le métal ou l'alliage métallique.
