popup.description2
High-entropy alloys in cathode species for ion-plasma and magnetron sputtering have been determined and manufactured. The influence of oxygen content in the mixture on the quantitative formation of high-entropy oxide phase in the coating obtained by cathodic sputtering of multicomponent FeCoNiAlVMo alloy in plasma of compressed vacuum-arc gas discharge is established. It is shown that in the optimum proportion the hardness of the coating is in the region of 34-35 GPa and exceeds the hardness of the mono oxides included in the alloy, and the reduced modulus of elasticity is 280-290 GPa. - arc discharge containing H2C2. It is established that the hardness of coatings of high-entropy carbide on the basis of multicomponent alloy FeCoNiAlVMo is at the level of 41-43 GPa and exceeds the hardness of the mono carbides that are included in the alloy.
