Abstract
A method for producing a tool coated with a hard coating, the method including the following steps: applying a TiAIN coating layer onto a substrate with a first magnetron sputtering process and applying a TixSi1-xN coating layer onto the TiAIN layer with a second magnetron sputtering process, where x is smaller than or equal to 0.85 and preferably between and including 0.80 and 0.70 whereas the second magnetron sputtering process is performed with power densities greater than 100 W/cm2 and as such is a HIPIMS process.
