Abstract
Un método de construccion una parte de metal completamente densa o un medio molde de metal, para unirlo con otro medio para formar un molde completo para fundir partes multiples. Los pasos de dicho método incluyen la colocacion de un patron en una base tubular del molde, la fundicion de un miembro de cerámica sobre las superficies críticas del patron, extraer el patron de dicha base del molde, cubrir las superficies críticas transferidas al miembro de cerámica con un metal pulverizado (24) que tiene una temperatura de fusion mayor que la temperatura de fusion de un metal de infiltracion (26), colocar una cantidad de un metal de infiltracion (26) sobre el metal pulverizado (24), colocar la base tubular del molde (10) en un horno en una temperatura suficiente para fundir el metal de infiltracion sin derretir el metal pulverizado, y extraer el miembro de cerámica (20) desde el primer extremo abierto de la base tubular del molde para exponer las superficies críticas. La cantidad de metal de infiltracion es suficiente para llenar los huecos entre las partículas del metal pulverizado cuando el metal de infiltracion es derretido, generando de este modo una parte de metal completamente densa. La parte de metal tiene superficies críticas transferidas desde el miembro de cerámica cuando el metal de infiltracion se solidifica. El polvo de metal también actua como un filtro para filtrar cualquier contaminacion o metal oxidado que se encuentre dentro del metal de infiltraciòn de modo que la contaminacion no manche la superficie acabada de la parte de metal completamente densa.
