  • Publication number: 20180112304
    Abstract: The present invention relates to a method for manufacturing a metal strip or sheet, including the steps of providing a substrate made from stainless steel; and depositing a chromium-nitride layer on the substrate by physical vapor deposition (PVD) in a deposition installation comprising a deposition chamber and a chromium target arranged in the deposition chamber. The deposition chamber has a deposition area with a length strictly smaller than the length of the deposition chamber and at least a first prohibited area. During the deposition, the chromium nitride is deposited on the substrate only in the deposition area and no chromium nitride is deposited on the substrate in the prohibited area.

  • Publication number: 20110094363
    Abstract: A ceramic cutting tool configured as multiphase ceramic with an improved resistance to wear of the edge area or edge layer consists of a base ceramic and of a sacrificial phase as well as eventually additives and primary hard material phases and an eventually multilayered edge area or edge layer resistant to wear, hard, not deposited made of at least one hard material phase, whereby the edge area is intimately intergrown with the starting ceramic and which is formed by aging the starting ceramic in a defined atmosphere.
