Abstract

La présente invention concerne un outil de terrassement ou de travail du sol, doté d'un corps allongé à l'extrémité avant duquel se trouve un élément de terrassement en métal dur. L'outil de l'invention présente des améliorations en ce que le métal dur comprend au moins une phase de matériau dur tel que WC, et un liant constitué de nickel/chrome ou cobalt/nickel/chrome. La proportion de chrome éventuellement utilisée vaut de 0 à 0,9 % en poids, de préférence d'environ 0,1 à 0,7 % en poids. Le liant cobalt/nickel/chrome comprend de 4 à 20 % en poids de la totalité du métal dur, le rapport cobalt/nickel valant de 90 Co: 10 Ni à 10 Co: 90 Ni, de préférence 70 Co: 30 Ni à 50 Co: 50 Ni.
