  • (Al, Cr, Ta)N coating for enhanced high temperature resistance
    Patent number: 9885106
    Abstract: A hard coating containing at least one layer including chromium, aluminum, tantalum and nitrogen as main components and a chemical composition (AlaCrbTac)N in which the following conditions are satisfied: a=x, (1?c), b=(1?x)·(1?c), 0.60?x?0.70, and 0.01?c?0.5. The layer has an X-ray diffraction peak intensity ratio of I200/(I200+I111)?0.25. The application also relates to a reactive arc ion plating PVD process for making the hard coating.

  • Ti—Al—Ta-based coating exhibiting enhanced thermal stability
    Patent number: 9506139
    Abstract: A wear resistant coating system including a tantalum-containing multilayered film having n A layers and m B layers, where n and m are integral numbers larger than I, deposited alternating one on each other. The multilayered film exhibits crystalline cubic structure, and is characterized in that the B layers include tantalum and the A layers exhibit a higher defect density than the B layers.
