چکیده انگلیسی
The (TiZrNbHfTa)N/WN multicomponent coatings were deposited by vacuum arc evaporation under different substrate bias (â90 and â280â¯V). X-ray photoelectron spectroscopy was used for analyzing of complex composition of investigated coatings by reflecting of atomic scale chemical interactions. The structural investigations showed the formation of a simple disordered solid solution in (TiZrNbHfTa)N layer, β-W2N phase in WN layer with fcc crystal structure and highly disordered bcc (1â¯1â¯0) and (2â¯2â¯0)-oriented high-entropy alloy phases, regardless of the applied bias potential. It was shown that with increasing of substrate bias from â90 to â280â¯V, there is a slight decrease of hardness from 34 to 31â¯GPa and increase of Young's modulus from 325 to 337â¯GPa, which can be explained by annihilation of point defects and precipitation of relatively softer metallic phase.
