METHOD FOR MANUFACTURING AN EXTRUSION DIE |
| 摘要 |
Method for producing an extrusion die having a functional surface for metal extrusion material, comprising the following steps: providing a die support body, depositing a weldable substance containing cobalt and/or nickel onto a subsection of the die support body by means of an effective bonding application process to produce an inseparable deposition layer, machining the deposition layer in a chipping and/or material removal process to form the functional surface of the extrusion die, and carrying out a CVD coating process with a reaction gas at least on the functional surface. |

1. Method for producing an extrusion die having a functional surface for metal extrusion material, comprising the following steps:
providing (10) a die support body (50), depositing (14) a weldable substance containing cobalt and/or nickel onto a subsection of the die support body by means of an effective bonding application process to produce an inseparable deposition layer (52), machining (20) the deposition layer in a chipping and/or material removal process to form the functional surface (54) of the extrusion die, and carrying out a CVD coating process (22) with a reaction gas at least on the functional surface. |
