A high-entropy alloy ZrTiCrNiCu and coating are synthesized by mechanical alloying. The microhardness of the ZrTiCrNiCu coating is not inferior and in most cases exceeds the hardness of highly entropic equiatomic alloys. The wear resistance of the ZrTiCrNiCu coating is 3⋅10 −4 g/min, which also meets the special steels for wear resistance. A high-entropy coating has a low coefficient of friction. They turn out to be anti-friction, which, in all likelihood, leads to energy savings. The surface energy, contact potential difference, and electron work function for high entropy coatings are first determined in the work.

In this work, a high-entropy alloy and CrZrTiNiCu coating were synthesized by mechanical alloying. It is shown that the microhardness of the CrZrTiNiCu coating is not inferior to and in most cases exceeds the hardness of high-entropy equiatomic alloys. The wear resistance of such a coating is 3·10-4 g/min, which also corresponds to special steels in terms of wear resistance. The high-entropy coating has a low coefficient of friction. It turns out to be antifrictional, which obviously leads to energy savings. For the first time, the surface energy, contact potential difference and work function of electrons for CrZrTiNiCu coating were determined.

“…For the manufacture of the target, various micropowders of the necessary metals were taken in equiatomic proportions and ground in a planetary ball mill according to the method described in [14]. Subsequently, from the obtained homogenized composition of the mixture, special tablets were formed on a hydraulic press (Fig.…”

The development of modern technologies in various industries cannot be imagined without the development and use of new materials, including new highly entropic alloys (HEA) and coatings based on them, as more advanced in terms of performance compared to traditional materials and coatings. Methods for producing various highly entropic alloys are described in many literature. Almost all such technologies at the moment cannot be applicable in the mass production of parts due to the high cost and lack of appropriate infrastructure and production technologies. However, obtaining coatings formed on the basis of highly entropic alloys for various parts of mechanisms and machines is currently a highly promising direction in improving the operational properties of work surfaces. The goal of this work is to create highly entropic coatings obtained by magnetron sputtering of special multicomponent targets. The paper shows the possibility of synthesis of coatings of the predicted composition and properties. A coating based on a matrix target made of 12Kh18N10T steel with pressed multicomponent Cr-Ni-Zr-Ti-Cu pellets was synthesized. The elemental composition of the coating and its properties were determined, the microhardness was measured, and the functional properties were established.
