  • Patent number: 11643717
    Abstract: A coated tool for hot stamping of coated or uncoated sheet metals, comprising a coated substrate surface to be in contact with the coated or uncoated metal sheet, wherein the coating in the coated substrate surface comprises one or more inferior layers and one or more superior layers, where the inferior layers are deposited closer to the substrate surface than the superior layers, and: the inferior layers are designed for providing load bearing capacity, the superior layers are designed for providing galling resistance, at least one superior layer is deposited having a multi-nanolayer structure wherein: one type of nanolayer is composed of at least 90 at.-% of chromium and nitrogen, a second type of nanolayer is composed of at least 90 at.-% of titanium, aluminum and nitrogen, a third type of nanolayer is composed of at least 90 at.-% of vanadium carbon and nitrogen.

  • Publication number: 20220106677
    Abstract: Coated tool for hot stamping of coated or uncoated sheet metals, in particular for hot stamping of AlSi- or Zn-coated sheet metals[KM2], comprising a coated substrate surface to be in contact with the coated or uncoated metal sheet, wherein the coating in the coated substrate surface is a multi-layer coating comprising one or more inferior layers and one or more superior layers, where the inferior layers are deposited closer to the substrate surface than the superior layers, whereas: —the inferior layers are designed for providing load bearing capacity, —the superior layers are designed for providing galling resistance, —at least one superior layer (layer 5) is deposited having a multi-nanolayer structure formed by sublayers of the type A, B and C, said three kind of sublayers being nanolayers deposited alternate one on each other forming a sequence of the type . . . A/B/C/A/B/C/A . . .
