Abstract

La invención provee un método para producir un artículo rígido sinterizado de metales duros que tiene un núcleo de una composición de metal duro de unaprimera clase, y al menos una capa superficial de un metal duro de una segunda clase, que comprende las etapas de: (a) preparar una lechada que contiene unpolvo de metal duro de la segunda clase en calidad de constituyente de la lechada en partículas, y un vehículo líquido que consiste esencialmente enhidrocarburos, incluyendo dicho vehículo líquido disolventes, agentes activadores de tensión superficial, aglutinantes y agentes plastificadores; (b)aplicar dicha lechada a una superficie de compacto verde, estando dicho compacto verde formado por dicho metal duro de primera clase; (c) permitir quela lechada se seque sobre dicho compacto verde para formar un compacto verde constituido por capas; y (d) sinterizar dicho compuesto verde constituido porcapas para formar el artículo rígido deseado. Se provee además el artículo rígido sinterizado de metales duros obtenido por el método.
