Abstract
Matériau composite résistant à l'usure, constitué de matériaux durs et/ou de métaux durs ainsi que d'une matrice métallique, de préférence en fer fritté, en acier fritté, en fonte de moulage ou en acier fondu au creuset, caractérisé en ce que le coefficient de dilatation thermique de la matrice métallique est supérieur à celui des matériaux durs, voire des métaux durs, et que le rapport entre le poids des matériaux durs et/ou des métaux durs, d'une part, et le poids de la matrice métallique, d'autre part, se Situe entre 1/1 et 1/0,1. Application, notamment, à la fabrication d'outils de perçage, de forage, et d'engins de travaux publics.
