The possibility of producing coatings of high entropic carbide by scattering multicomponent alloy in plasma of compressed vacuum–arc discharge has been shown. It is defined that the hardness of coatings from high-entropic carbide based on TiZrHfVNbTa multicomponent alloy is 43–48 GPa and exceeds the hardness of monocarbides of metals that enter into the composition of the alloy. The friction coefficient for the carbide high-entropic coating based on the TiZrHfVNbTa alloy at the loads 2.2 to 5.2 N is 0.14–0.16.

By studies of materials based on the Ti₃AlC₂ MAX phase containing inclusions of titanium carbide it has been shown that as a titanium carbide content increases from 2 to 99%, the nanohardness and Young modulus of the material increase from 2.0 ± 0.4 to 23.6 ± 1.2 GPa and from 137 ± 21 to 447 ± 11 GPa, respectively. The exponent in the equation of creep for these samples has been found to vary from 104 to 140, which indicates that mechanical properties of the material and, hence, of the Ti₃AlC₂ MAX phase depend on the strain rate only slightly. The formation of broad hysteresis loops has been observed in the cyclic loading/unloading of the indenter for samples consisting mainly of the Ti₃AlC₂ MAX phase. This points to serious losses in elastic energy of the MAX phase in strain cycling and, hence, the prospects of the MAX phase application as a damping material. It has been found that the microhardness of a sample consisting of 98% Ti₃AlC₂ produced by sintering under a load of 4.9 N was 2.1 GPa and its fracture toughness was high (no cracks from the indent corners were observed even under a load of 149 N). Microhardness and fracture toughness of the material consisting of 71% Ti₃AlC, 6% Ti₂AlC, and 23% TiC were 3.0 ± 0.6 GPa and 4.3 ± 1.4 MPa·m^1/2, respectively.
