Özet:

 

An extensive study of the surface oxidation process on   the properties of TiVN/VN multilayer coatings deposited by RF magnetron   sputtering on Mg alloys was performed. TiVN/VN multilayer coatings with a   total thickness of 660 nm and different layer numbers of 5, 11, and 33 were   oxidized by annealing at 450K under partial oxygen pressure. Electronic,   mechanical, and tribological properties of these coatings were characterized   by X-ray photoelectron spectroscopy (XPS), scanning electron microscope,   nanoindentation measurements, and scratch tester. The experimental results   showed that the oxidation of TiVN/VN multilayer coatings leads to better   performance in terms of surface roughness, hardness, and wear. The hardness   of the coating increased significantly (up to 1400 HV) with the oxidation of   the surface due to the release of stresses between each layer after in situ   annealing. The decline of the friction coefficient after oxidation can be   attributed to the formation of a self-lubricating V22_{2}O55_{5} layer on   the surface, the presence of which was confirmed by XPS. The findings in   this work reveal a new technique for applying a better thin film coating for   industrial applications of Mg alloys.
