Title (EN) A ROTARY EARTH STRATA PENETRATING TOOL WITH A CERMET INSERT HAVING A Co-Ni-Fe-BINDER
(FR) OUTIL ROTATIF DE PENETRATION DE COUCHE TERRESTRE AVEC TREPAN RAPPORTE EN CERMET CONTENANT UN LIANT Co-Ni-Fe
Abstract: front page image
(EN)A rotary tool that includes an elongate tool body and a hard insert (16) affixed to the tool body is disclosed. The hard insert comprises a WC-cermet comprising tungsten carbide and about 5 wt.% to 19 wt.% Co-Ni-Fe-binder. The Co-Ni-Fe-binder is unique in that even when subjected to plastic deformation, the binder substantially maintains its face centered cubic (fcc) crystal structure and avoids stress and/or strain induced transformations.
(FR)Cet outil rotatif se compose d'un corps d'outil allongé et d'un trépan dur rapporté (16) fixé au corps de l'outil. Le trépan dur rapporté est fabriqué en cermet WC contenant du carbure du tungstène et environ 5 à 19 % en poids d'un liant Co-Ni-Fe. Le liant Co-Ni-Fe est unique en ce que, même soumis à des déformations plastiques, il conserve sensiblement intact son système cristallin cubique à faces centrées (fcc) et évite les transformation dues à l'effort et/ou aux contraintes.
