Abstract
Se incorporan inhibidores de crecimiento de grano que incluyen carburo de vanadio, carburo de cromo, carburo de tántalo y carburo de niobio a una matriz de carburo de cobalto/tungsteno durante la formacion de la matriz de carburo de cobalto/tungsteno. Se forma un polvo precursor combinado en solucion una composicion de cobalto, una composicion de tungsteno y una composicion de metal inhibidor de crecimiento de grano, la cual es secada por aspersion. El compuesto precursor después es carburizado en monoxido de carbono y dioxido de carbono para formar la matriz de carburo de cobalto/tungsteno. Después, esta es carburizada además en un gas hidrogeno de hidrocarburo a una temperatura elevada para hacer que el metal inhibidor de crecimiento de grano esté presente para formar carburo. La segunda etapa de carburizacion se conduce con un gas de carburizacion que tiene una actividad de carbono mayor de aproximadamente 2, durante un período de tiempo relativamente corto de 900 degree C a 1000 degree C.
