A method of additive manufacturing can include forming a machine part having a first portion formed from a cast iron material; forming a second portion adjacent the first portion formed of a combination of the cast iron material and a different material; and forming a third portion adjacent the second portion formed of only the different material, wherein the third portion is located at a predetermined critical area of the machine part. Un procédé de fabrication additive peut comprendre la formation d'une pièce de machine ayant une première portion formée à partir d'un matériau de fonte ; la formation d'une deuxième portion adjacente à la première portion, formée d'une combinaison du matériau de fonte et d'un matériau différent ; et la formation d'une troisième portion adjacente à la deuxième portion, formée uniquement du matériau différent, la troisième portion étant située au niveau d'une zone critique prédéfinie de la pièce de machine.
