“…8 Different from IV-carbides, NbC with a slightly off stoichiometric Nb/C (1 : 1) ratio can show enhanced hardness. 20 Our C-rich NbC films may help to improve the hardness. Simultaneously, the Young's modulus of NbC films is also measured as a function of the penetration depth.…”

“…There were 2 important factors causing the effect of carburizing on Ti-5Al-2.5Sn to be the greatest among the 3 alloys. TiC; which its hardness (³3000 HV 18,19,39) ) is the highest in comparison with VC (³2500 HV 33,39,40) ) and Ti 2 AlC (³500 HV 41) ); was the only carbide formed and Ti content of the alloy was the highest among the 3 alloys promoting the largest quantity of TiC formation. These factors also caused the effect of carburizing on Ti-10V-2Fe-3Al to be greater than that on Ti-38Al.…”

Tribological behavior of Ti-5Al-2.5Sn, Ti-10V-2Fe-3Al and Ti-38Al carburized via current heating technique with graphite powders was studied. In carburizing, the direct current was applied across the graphite powders and alloys with a fixed electric power from 120 to 180 W for 20 min in argon atmosphere. The alloys were characterized using XRD, SEM, and hardness tester. Tribological behavior of the alloys was examined by pin-on-disk tribological test. Formation of TiC, TiC with VC and Ti 2 AlC with TiC on Ti-5Al-2.5Sn, Ti-10V-2Fe-3Al and Ti-38Al, respectively, could improve surface hardness and reduce friction coefficient leading to improve wear resistance of the alloys. Coatings of TiC totally exhibited higher wear resistance than that of Ti 2 AlC. Improvement of wear resistance was influenced by quality of coatings which could be sorted in descending as TiC, TiC with VC and Ti 2 AlC with TiC in the carburized Ti-5Al-2.5Sn, Ti-10V-2Fe-3Al and Ti-38Al, respectively.

Vanadium is a biologically active product with significant industrial and biological applications. Vanadium is found in a variety of minerals and fossil fuels, the most common of which are sandstones, crude oil, and coal. Topological descriptors are numerical numbers assigned to the molecular structures and have the ability to predict certain of their physical/chemical properties. In this paper, we have studied topological descriptors of vanadium carbide structure based on ev and ve degrees. In particular, we have computed the closed forms of Zagreb, Randic, geometric-arithmetic, and atom-bond connectivity (ABC) indices of vanadium carbide structure based on ev and ve degrees. This kind of study may be useful for understanding the biological and chemical behavior of the structure.
