Frictional properties of multielement coatings (TiZrHfYNbTa)N
The influence of pressure of nitrogen atmosphere on the structural and phase state and properties of vacuum-arc nitride coatings Ti-Zr-Hf-V-Nb-Ta has been studied. The multi-element nitride coatings deposited in nitrogen, are single-phase with a cubic face-centered cubic lattice (structural type NaC...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The influence of pressure of nitrogen atmosphere on the structural and phase state and properties of vacuum-arc nitride coatings Ti-Zr-Hf-V-Nb-Ta has been studied. The multi-element nitride coatings deposited in nitrogen, are single-phase with a cubic face-centered cubic lattice (structural type NaCl) excluding the dropping component. The maximum hardness (42.2 GPa) is achieved for the nitride coatings deposited by vacuum arc evaporation (Ti, Zr, Hf, V, Nb, Ta) of the alloy at the pressure of nitrogen of 0.3 Pa. The tribotechnical characteristics have been studied during high temperature tests. It was found that wear resistance of the coatings is higher at T = 500 °C and T = 700 °C due to formation of oxide tribofilms on the surface, which act as a solid lubricant during testing. |
