Abstract

SE DESCRIBE UNA PIEZA METALICA DE POLVO FERREO INFILTRADA CON COBRE O ALEACION DE COBRE QUE TIENE, DESPUES DE LA INFILTRACION, UNA POROSIDAD INFILTRADA RESIDUAL INFERIOR A APROXIMADAMENTE 7% EN VOLUMEN Y UN TAMAÑO MAXIMO DE PORO DE DICHA POROSIDAD INFERIOR A APROXIMADAMENTE 125 MICROMETROS, TOMANDOSE DICHOS VALORES DESDE EL PEOR CAMPO DE VISION EN UN AEREA FUNCINALMENTE CRITICA DE DICHA PIEZA, LA CUAL TIENE PREFERIBLEMENTE UNA DENSIDAD GLOBAL DE AL MENOS 7,50 G/CM3 Y UNA PROFUNDIDAD DE DIFUSION DE COBRE EN LA MATRIZ DE ACERO INFERIOR A APROXIMADAMENTE 4 MICROMETROS, DETERMINADA POR ATAQUE QUIMICO, O INFERIOR A APROXIMADAMENTE 8 MICROMETROS, DETERMINADA POR ANALISIS DE RAYOS X DISPERSIVOS DE ELECTRONES. DICHAS PIEZAS SE OBTIENEN TIPICAMENTE LLENANDO UNA MATRIZ CON MATERIAL FERREO, PRENSANDO ESTE HASTA AL MENOS 80% DE LA DENSIDAD TEORICA, SINTERIZANDO DICHO PRODUCTO E INFILTRANDO LUEGO EL POLVO METALICO CON INFILTRANTE DE COBRE O ALEACION DE COBRE. LA SINTERIZACION E INFILTRACION PUEDEN REALIZARSE SIMULTANEAMENTE.
