1. Introducción: El papel del polvo de hierro en el prensado y la sinterización
El polvo de hierro es un material fundamental en la industria pulvimetalúrgica (PM), ampliamente utilizado en procesos de prensado y sinterización para crear componentes de precisión con excelentes propiedades mecánicas. Estos componentes se utilizan en aplicaciones de automoción, aeroespaciales, maquinaria industrial y electrónica de consumo.
En pulvimetalurgia, el prensado consiste en compactar polvo de hierro en una matriz para darle la forma deseada. A continuación, la sinterización calienta la pieza compactada por debajo de su punto de fusión, lo que une las partículas y aumenta su resistencia.
