Abstract

MÉTODO DE FORMAÇÃO DE UM MATERIAL, MATERIAL COMPÓSITO POLICRISTALINO, E MATERIAL COMPÓSITO DE NITRETO DE BORO CÚBICO POLICRISTALINO. A presente invenção refere-se aos compósitos e compostos de rutênio de tungstênio e aos métodos de formação dos mesmos. Os pós de tungstênio e rênio são misturados juntamente e sinterizados em temperatura elevada e pressão elevada para formar um único composto. Um material ultraduro pode também ser adicionado. O tungstênio, rênio, e material ultraduro são misturados juntamente e em seguida sinterizados em temperatura elevada e pressão elevada.
