Abstract

LA PRESENTE INVENCION SE RELACIONA CON UN METODO DE FABRICACION DE PIEZAS DE METAL CON UNA DIMENSION APROPIADA POR MEDIO DE SINTERIZAR UNA MEZCLA DE UN MATERIAL EN POLVO QUE CONSISTE EN UN METAL DEL GRUPO DE ACERO, UN COMPUESTO DE FOSFORO Y COBRE, Y UNA ALEACION DE COBRE. LA PIEZA ES PRODUCIDA POR MEDIO DE LA SINTERIZACION POR LASER DEL AREA SELECCIONADA CAPA A CAPA. LA SINTERIZACION TIENE LUGAR EN UNA ATMOSFERA QUE CONTIENE UN COMPUESTO GASEOSO DE UN METAL DEL GRUPO DE ACERO, POR LO QUE EL COMPUESTO SE DESCOMPONE A UNA TEMPERATURA DE SINTERIZACION Y EL METAL DEL GRUPO DE ACERO SE DEPOSITA EN DICHA MEZCLA EN POLVO DURANTE LA SINTERIZACION.
