Abstract

LA INVENCION SE REFIERE A UNA MEZCLA PULVERULENTA ADECUADA PARA UTILIZACION EN UN PROCEDIMIENTO DE SINTERIZACION Y COMPACTACION, QUE COMPRENDE TRES CONSTITUYENTES. EL PRIMER CONSTITUYENTE ESTA PRACTICAMENTE EXENTO DE CARBONO, ESTA FORMADO POR UNO O MAS POLVOS ALEADOS Y PRESENTA UNA COMPOSICION COMPRENDIDA ENTRE LOS SIGUIENTES RANGOS, EXPRESADOS EN % EN PESO: 8 A 12 DE CROMO, 0,5 A 3 DE MOLIBDENO, OPCIONALMENTE HASTA EL 10 % EN TOTAL DE AL MENOS UN METAL SELECCIONADO A PARTIR DE VANADIO, COBALTO Y TUNGSTENO, UN MAXIMO DE OTROS 2 MATERIALES INCLUYENDO IMPUREZAS, Y EL RESTO ES HIERRO. EL SEGUNDO CONSTITUYENTE ESTA FORMADO POR UN POLVO DE CARBONO SUFICIENTE PARA LOGRAR UN CONTENIDO TOTAL DE CARBONO DE LA MEZCLA DEL 1,5 AL 3,0 % EN PESO. EL TERCER CONSTITUYENTE ESTA FORMADO POR LA SUFICIENTE CANTIDAD DE POLVO FERROFOSFOROSO, PARA PRODUCIR UN CONTENIDO TOTAL DE FOSFORO EN LA MEZCLA DEL 0,1 AL 0,5 % EN PESO.THE INVENTION REFERS TO A SUITABLE PULVERULENT MIXTURE FOR USE IN A SINTERIZATION AND COMPACTION PROCEDURE, WHICH INCLUDES THREE CONSTITUENTS. THE FIRST CONSTITUENT IS PRACTICALLY FREE OF CARBON, IS FORMED BY ONE OR MORE ALLOY DUST AND PRESENTS A COMPOSITION INCLUDED BETWEEN THE FOLLOWING RANGES, EXPRESSED IN WEIGHT: 8 TO 12 CHROME, 0.5 TO 3 MOLIBDEN, OPTIONALLY UP TO 10% IN TOTAL OF AT LEAST ONE METAL SELECTED FROM VANADIO, COBALTO AND TUNGSTEN, A MAXIMUM OF OTHER 2 MATERIALS INCLUDING IMPURITIES, AND THE REST IS IRON. THE SECOND CONSTITUENT IS FORMED BY A SUFFICIENT CARBON POWDER TO ACHIEVE A TOTAL CARBON CONTENT OF THE MIXTURE OF 1.5 TO 3.0% BY WEIGHT. THE THIRD CONSTITUENT IS FORMED BY THE SUFFICIENT AMOUNT OF FERROPHOSPHOROUS POWDER, TO PRODUCE A TOTAL CONTENT OF PHOSPHORUS IN THE MIXTURE OF 0.1 TO 0.5% BY WEIGHT.
