Production and mechanical properties of high-entropic carbide based on the TiZrHfVNbTa multicomponent alloy

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...

Description
Summary: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.
