Abstract

Patente de Invenção:<B>"FERRAMENTA DE CORTE DE NITRETO DE BORO CúBICO POLICRISTALINO"<D>. Uma ferramenta de corte de nitreto de boro cúbico policristalino é de 50 a 85% em peso de cristais de nitreto de boro cúbico ligados entre si como uma massa policristalina. Uma fase de suporte misturada com o nitreto de boro cúbico policristalino é constituída de 15 a 40% em peso de um material refratário que é, de preferência, carbonitreto de titânio ou carbonitreto de titânio e alumínio. A composição de partida também compreende de 4 a 10% em peso de Co~ 2~Al~ 9~. Os pós mistos desses ingredientes são tratados a uma temperatura Na faixa de 1.100 a 1.250°C, que aumenta, significativamente, o teor de nitrogênio e reduz o teor de carbono do carbonitreto de titâni ou do carbonitreto de titâmio e alumínio. Em vez dos pós mistos dos materiais de partida, podem ser usadas partículas revestidas, tais como nitreto de boro cúbico revestido com cabonitreto de titânio, ou carbonitreto de titânio revestido com cobalto, alumínio ou alumínio de cobalto. Nitreto de boro hexagonal também pode ser substituído como um material de partida para uma parte do nitreto de boro cúbico.
