The paper deals with multilayer CrN/AlN coatings fabricated by the plasma-assisted vacuum-arc deposition onto a WC–8Co alloy substrate. The use of a screen for separating alternately Cr and Al flows, allows to create a multilayer coating structure with CrN and AlN nanolayers. The X-ray diffraction analysis shows that the structure of obtained coatings consists of CrN and AlN phases with the face-centered cubic crystal structure. It is found that a 5 rpm rotation speed of the turning table is the best and provides the most appropriate ratio between the thickness of CrN and AlN layers and the ratio between their phase compositions. This allows minimizing the wear rate intensity of the coatings. The in situ synchrotron X-ray diffraction analysis confirms the presence of CrN and AlN phases in the temperature range of ~1075 to 1080°C.
