| 摘要 |
A method for producing a coating of one or more layers on an extrusion die as a substrate body of a heat-resistant and/or long-term heat-resistant steel material by means of chemical vapour deposition (CVD), comprising the steps of: providing the substrate body from hot-work tool steel, which is intended for interacting with ductile extrusion metal, introducing a first reaction gas, comprising a metal, in particular titanium, into a reactor receiving the substrate body, to provide a coating metal, introducing a second reaction gas, comprising a carbon compound, into the reactor, to provide carbon for the coating, wherein the first and/or the second reaction gas or a further reaction gas provide(s) nitrogen for the coating, and carrying out a CVD coating process with the reaction gases. |
