The paper focuses on the dual high-power impulse magnetron sputtering of TiAlN coatings using short pulses of high power delivered to the target. The surface morphology, elemental composition, phase composition, hardness, wear resistance, and adhesive strength of TiAlN coatings with different Al contents were investigated on WC-Co substrates. The heat resistance of the TiAlN coating was determined with synchrotron X-ray diffraction.

The Al/Cr ratio in the coating depends on the substrate position relative to magnetrons. It is shown that the higher Al content in the (CrAl)N coating improves its hardness from 17 to 28 GPa.
