Abstract
LAS ALEACIONES CONSOLIDADAS DE NITROGENO, ESPECIALMENTE ACEROS, SE OBTIENEN MEDIANTE EL CALENTAMIENTO DE UNA COMBINACION DE PARTICULAS METALICAS Y UN DONOR (ELEMENTO DONANTE) DE NITROGENO, TAL COMO NITRURO DE CROMO, PARA OBTENER NITROGENO DISPONIBLE, COMO UNA SUSTANCIA DISUELTA EN LAS PARTICULAS. LAS PARTICULAS PUEDEN OBTENERSE COMO UNA PREFORMA PERMEABLE PARA EL PROCESO. EL NITROGENO DISUELTO CONDUCE A UNA DUREZA MEJORADA, OBTENIENDOSE TAMBIEN UNA ADICIONAL RESISTENCIA MEDIANTE LA INCLUSION DE UN DISPERSANTE, TAL COMO ITRIA, EN LAS PARTICULAS.
