  • Anti-abrasive layer
    Patent number: 7541101
    Abstract: An anti-abrasive layer which is useful for tools contains nitrides of the metal elements Cr, Ti and Al; and at least one element (?); wherein a proportion of Cr in said anti-abrasive layer is more than 65 at %; a proportion of Al is 10 to 25 at %; and a proportion of Ti is 10 to 25 at %, based on a total amount of metal atoms in said anti-abrasive layer.
    Type: Grant
    Filed: April 14, 2006
    Date of Patent: June 2, 2009
    Inventor: Frank-R Weber
  • Wear-resistant coating for metal-removing tools, particularly for rotary metal-cutting tools
    Patent number: 7217466
    Abstract: The invention concerns a wear-resistant coating on rotary metal-cutting tools such as drill bits, countersinks, milling cutters, screw taps, reamers, etc. The coating according to the invention consists essentially of nitrides of Cr, Ti and Al with a unusually high share of Cr atoms, namely 30 to 60% referred to the totality of metal atoms. In multilayer coatings and even more in coatings made of homogeneous mixed phases, this high Cr share results in particularly large tool life distances for the tools hardened with these coatings. These tools exhibit their superiority particularly during dry use without cooling lubricants or with minimal lubrication.
