| description | A method of treating a cemented carbide insert for rock drilling and mineral cutting comprising a core of cemented carbide and a surface zone of cemented carbide wherein the core further contains eta-phase and the surface zone is free of eta-phase, and wherein the mining insert is subjected to a surface hardening process wherein the surface hardening process is executed at an elevated temperature of or above 50°C.
L'invention concerne un procédé de traitement d'un insert en carbure cémenté destiné au forage de roche et à la découpe de minéraux qui comprend un noyau de carbure cémenté et une zone de surface de carbure cémenté, le noyau contenant en outre une phase êta et la zone de surface étant exempte de phase êta, et l'insert pour extraction minière étant soumis à un processus de durcissement de surface, le procédé de durcissement de surface étant exécuté à une température élevée, supérieure ou égale à 50 °C. |
