Abstract
La invención se refiere a un método para producir una herramienta de conformado en frío, particularmente para aceros de súper alta resistencia de conformado en frío, en donde la herramienta de conformado en frío es la herramienta superior y/o inferior de un juego de herramientas de conformado, en donde la herramienta de conformado en frío se hace de un material metálico y tiene una superficie de conformado que se diseña de tal manera que una hoja de metal formada tiene el contorno final deseado del componente, caracterizado porque una capa de material duro se deposita sobre la superficie de conformado de la herramienta de conformado por medio de deposición física en fase gaseosa, en donde la capa de material duro consiste de una capa adhesiva de nitruro de titanio y capas alternas de nitruro de aluminio y titanio y nitruro de aluminio y cromo depositadas sobre la misma, en donde una capa superior de nitruro de titanio o, alternativamente, una capa superior de nitruro de titanio y carbono se deposita como capa final como la superficie exterior más exterior orientada hacia una pieza de trabajo que se va a conformar.
