High-performance coating for high strength steel cold-forming metal

摘要

The present invention relates to the metal forming tool of the cold forming for high strength steel or the coating of metal forming component, wherein described coating includes the bottom (20) containing CrN and the top layer (30) containing TiCN, wherein compared with the top layer (30), the bottom (20) is deposited closer to the base material (1), it is unique in that the bottom (20) by showing that the oxygen-enriched chromium nitride of the cubic structure with preferable (200) direction forms, and the top layer (30) is made up of hydrogen-rich titanium carbonitride.The invention additionally relates to the method for depositing the coating according to the present invention.
