ABSTRACT:
A method for coating a tool or tool part, includes providing a base structure of the tool or the tool part at a temperature of 850° C. to 950° C. and applying at least one layer to the base structure. One or more layers of the at least one layer is formed of a metal carbonitride of composed of at least one of titanium, zirconium, hafnium, vanadium, niobium, tantalum and chromium. The one or more layers of the at least one layer is deposited by a deposition of a gas containing methane, nitrogen and at least one metal compound. After beginning the applying, the temperature is increased by at least 40° C. to an increased temperature and the deposition is continued for a time at the increased temperature.
