Title (EN) METHODS OF FORMING AND REPAIRING CUTTING ELEMENT POCKETS IN EARTH-BORING TOOLS WITH DEPTH-OF-CUT CONTROL FEATURES, AND TOOLS AND STRUCTURES FORMED BY SUCH METHODS
(FR) PROCÉDÉS DE FORMATION ET DE RÉPARATION DE POCHES POUR ÉLÉMENTS DE COUPE DANS DES OUTILS DE FORAGE POSSÉDANT DES ÉLÉMENTS DE COMMANDE DE LA PROFONDEUR DE COUPE, ET OUTILS ET STRUCTURES FORMÉS À L'AIDE DE CES PROCÉDÉS
Abstract:
(EN) Methods of forming and repairing earth-boring tools include providing wear-resistant material over a temporary displacement member to form a cutting element pocket in a body and a depth-of-cut control feature using the wear-resistant material. In some embodiments, the wear-resistant material may comprise a particle-matrix composite material. For example, a hardfacing material may be built up over a temporary displacement member to form or repair a cutting element pocket and provide a depth-of-cut control feature. Earth-boring tools include a depth-of-cut control feature comprising a wear-resistant material. The depth-of-cut control feature is configured to limit a depth-of-cut of a cutting element secured within a cutting element pocket partially defined by at least one surface of the depth-of-cut control feature. Intermediate structures formed during fabrication of earth-boring tools include a depth-of-cut control feature extending over a temporary displacement member.
(FR) La présente invention concerne des procédés de formation et de réparation d'outils de forage qui consistent à disposer un matériau résistant à l'usure sur un élément de déplacement temporaire afin de former une poche pour élément de coupe dans un corps, et à fournir un élément de commande de la profondeur de coupe utilisant le matériau résistant à l'usure. Dans certains modes de réalisation, le matériau résistant à l'usure peut contenir un matériau composite de matrice de particules. Un matériau de durcissement de surface peut, par exemple, être disposé sur un élément de déplacement temporaire afin de former ou de réparer une poche pour élément de coupe et fournir un élément de commande de la profondeur de coupe. Les outils de forage comprennent un élément de commande de la profondeur de coupe contenant un matériau résistant à l'usure. L'élément de commande de la profondeur de coupe est conçu de manière à limiter la profondeur de coupe d'un élément de coupe situé dans une poche pour élément de coupe partiellement définie par au moins une surface de l'élément de commande de la profondeur de coupe. Les structures intermédiaires formées pendant la fabrication des outils de forage comprennent un élément de commande de la profondeur de coupe qui s'étend sur un élément de déplacement temporaire.
