“…While the peaks located at 43° and 73° correspond to a W2C hexagonal structure (PDF 04-014-5679). The atomics radius of tungsten and titanium are similar, thus are easily formed into the Ti-W-C ternary system [28]. The spectra of the n = 1 bilayer (orange line) showed an intense peak with a preferential plane (111) is observed corresponding to the TC2 structure.…”

Nitride and carbide ternary coatings improve the wear and corrosion resistance of carbon steel substrates. In this work, Ti-W-N and Ti-W-C coatings were deposited on AISI 1060 steel substrates using reactive radio frequency (RF) magnetron sputtering. The coatings were designed as monolayers, bilayers, and multilayers of 40 periods. The coatings were obtained with simultaneous sputtering of Ti and W targets. The microstructure, composition, and electrochemical properties were investigated by techniques such as X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), atomic force microscopy (AFM), electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization. XRD results shower a mix of binary TiN and W2N structures in the Ti-W-N layer, a ternary phase in Ti-W-C layers, in addition of a quaternary phase of Ti-W-CN in the multilayers. The analysis of the XPS demonstrated that the atomic concentration of Ti was more significant than W in the Ti-W-N and Ti-W-C layers. The lowest corrosion rate (0.19 mm/year−1) and highest impedance (~10 kΩ·cm2) out of all coatings were found in n = 40 bilayers. In the simulation of equivalent electrical circuits, it was found that the Ti-W-N coating presented three processes of impedance (Pore resistance + Coating + Inductance). However, the multilayer (n = 40) system presented a major dielectric constant through the electrolyte adsorption; therefore, this caused an increase in the capacitance of the coating.

Hard coatings based on the multiphase W‐Ti‐Si‐C system have been obtained by combined magnetron sputtering and ion implantation process (CMSII). The coatings have been produced from complex targets having a variable SiC content (5 and 10 wt.‐%). Their characterization included chemical and structural analysis by X‐ray diffraction (XRD), and glow discharge optical emission spectrometry (GDOES), scanning electron microscopy (SEM) investigation, and microhardness measurements. The coating produced from a target with 5% SiC showed a multiphase structure consisting of W2C, W3C, and WC1 − x phases, whereas the coatings produced from target with 10% SiC revealed a multiphase structure of (W,Ti)C1 − x. The microhardness of the coatings was in the range of 2 250–3 500 HV 0.05. The layers were subjected to oxidation tests performed by heating in air at temperatures up to 920 °C. The microhardness evolution after each cycle of heating was studied.

W-10Ti alloy was prepared by hot press sintering using W-TiH 2 powders milled for 24 h under argon atmosphere. The effect of sintering temperature on the phase constituents and the microstructure of the alloys was characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The microhardness of W-rich phase, electrical resistivity and impurity (C, O) contents of W-10Ti alloy were determined. The results show that the amount of W-Ti solid solution, the microhardness of the W-rich solid solution and the resistance of W-10Ti alloy increase with an increase of sintering temperature. At 1300°C, W-10Ti alloy has the maximum microhardness value of 333 HV 0.05 , the O content of 360 ppm and C content of 200 ppm.
