The temperature ranges of structural transformations in WC-Co and Ti1-xAlxNin the process of cathode-arc evaporation are analyzed. The limiting values of the WC-Co temperature before the deposition of the coating correspond to 773 ... 873 K, after which the hardness of WC-Co and, as a consequence, the hardness of the composition WC-Co / Ti1-xAlx deteriorates. Analysis of the coating structural transformations made it possible to establish the structuring stages of the Ti1-xAlx coating during its deposition. Wear test was carried out for Ti1-xAlx coatings formed at each structuring stage. Wear test were carried out according to the finger-disk scheme at 300 K in coolant-cutting fluid on a laboratory friction machine. The wear behavior of the Ti1-xAlx coating are unstable at 773 K, then improve at 773 ... 853 K, stabilize with an increase in temperature to 963 K. The nanostructured Ti1-xAlx coating formed in the temperature range T sub/T m = 0.18... 0.23have the best complex of wear properties in comparison with analogues.
