Beschreibung
Zusammenfassung:	A down hole drill bit that includes a plurality of cutting elements mounted on a cutting structure, wherein at least one of the plurality of cutting elements comprises a wear resistant material, the wear resistant material comprising coarse grains disposed in a binder matrix phase, wherein the binder matrix phase comprises nanoparticles dispersed therein is disclosed. La présente invention concerne un trépan de fond de trou comportant une pluralité d'éléments de coupe montés sur une structure de coupe, au moins un de la pluralité d'éléments de coupe comportant un matériau résistant à l'usure. Le matériau résistant à l'usure comporte des grains grossiers disposés dans une phase matricielle de liant, la phase matricielle de liant comportant des nanoparticules qui y sont dispersées.
