Abstract (en)
[origin: EP0924010A1] The mold structure is solid-solution annealed, the wear resistant layer is produced on the mold structure and the mold structure is hardened. The hardness of the wear resistant layer (7) of the mold decreases with the distance from the layer surface (8) towards the mold structure (5). The method for producing a mold with a mold structure (1) consisting of a hardenable copper alloy, and an interior wear resistant layer (7) consisting of chromium involves the following steps: a) the mold structure is solid-solution annealed; b) the wear resistant layer is produced on the mold structure; c) the mold structure is hardened. The hardness of the wear resistant layer (7) of the mold decreases with the distance from the layer surface (8) towards the mold structure (5).
