“…Consequently, coatings with lower vanadium and titanium content, corresponding to smoother systems, are anticipated to have reduced biofilm accumulation on their surfaces. This would be beneficial, for example, in cases of dental implants to prevent periimplantitis [12][13][14].…”

The research focuses on the electrochemical behavior of TiVN trilayers in a liquid that simulates a physiological environment (blood plasma). TiVN films are obtained through Physical Direct Current Vapor (PVD) Deposition on titanium bases, depositing TiN and VN layers as an intermediate layer during the procedure. Impedance measurements are carried out before and during the wear test to determine the impact on the sample. The results show that the TiVN trilayer enhances corrosion resistance according to the time of exposure to the electrolyte. Initially, the load resistance (Rct) was 10.50 Ohms, but after 16 days, the Rct rose markedly to 13.87 Ohms, signaling an advance in corrosion resistance, a valuable property for wide applications.

“…Other option consists in including Al, forming compounds as TiAlN coatings that, compared to TiN coatings have exhibited a better wear resistance, high oxidation temperature and high binding force (Kumar, 2015). On the other hand, in the literature it was found that, by adding V to TiN, an improvement can be observed in the mechanical and tribological performance (Montero-Ocampo, 2015). Combining the last two options, adding Al and V, a better performance can be obtained, decreasing the coefficient of friction (COF) of the surface at higher temperatures (Kumar, 2015); for instance, including V to TiAlN and producing a TiAlVN solid solution, in a face-centered cubic (fcc) structure, a material that exhibits high hardness and Young's modulus can be obtained (Pfeiler-deutschmann, 2015).…”

Ti/TiAlV/TiAlV(N) coatings were deposited by D.C magnetron sputtering technique. This experiment was carried out on 316L stainless steel substrates, and it was produced varying the working pressure, in an environment composed by a mixture of Ar/N2. While Ti and TiAlV layers were produced at a constant pressure, TiAlV(N) layers were grown at 0.6, 0.8, 0.9 and 1.0 Pa, for samples M1, M2, M3 and M4, respectively. After the production, morphological, compositional and structural properties of coatings were studied using techniques as x-ray diffraction (XRD), energy dispersive spectroscopy (EDS), and atomic force microscopy (AFM). Next, mechanical and tribological properties such as hardness, Young’s modulus, coefficient of friction, and adherence were evaluated, using nanoindentation, scratch test and ball on disc methods. XRD analysis evidenced that coatings crystallized in a salt rock FCC structure, and the crystallite size tended to increase with the increase of pressure. The XPS analysis allowed to demonstrate the presence of the doublets corresponding to metallic aluminum. Titanium was also found as well as the presence of oxygen as an oxidizing element of the coating.  Regarding to the morphological analysis, it was observed an increase of the roughness when the coatings were grown, compared with the stainless substrates; moreover, no significant influence of the small pressure variation was observed on properties as hardness, coefficient of friction, and critical load.

“…Different alloy films are targeted by scientists. They have studied the tribological and mechanical properties of TiVN, Cr 2 N-11Ag, Ti-6Al-4V, Cr-Ti-B-N, Ti/TiB 2 , and Mo-Ru [4][5][6][7][8][9] films with factors changing. Besides the material of films, films with different structures have been tested like nano-multilayer coatings.…”

In this article, the specimen of Q235 (low carbon steel, C 0.22%, Mn: 0.3%-0.8%, Si 0.3%, P 0.045%, S 0.05%) has been tested in in situ tensile tests. Especially, different types of scratches are prefabricated with 1, 2, and 3 mm in depth. In addition, three scratch angles (u = 0°, 45°, and 90°) are adopted to explore the changes of tensile strength. The cross profile of the scratch groove is measured with in situ observation method (Olympus DSX500), which is taken as an important indicator to verify the experiments. According to the results of experiments, scratch depth and angle can influence the tensile strength of material. When the depth and scratch angle increase, there is a decrement in the value of tensile strength. This indicates that the surface damage really has effect on the tensile strength of specimen.
