In HIPIMS process, the bias voltage has an effect on the coating properties.
Chemical composition of the TiAlN coating changes by increasing the bias voltage.
The re-sputtering phenomenon has an influence on the TiAlN coating properties.
The best mechanical properties of TiAlN was obtained at the bias voltage of −150 V.
The best tribological properties of TiAlN was achieved at the bias voltage of −100 V.
