“…A laser scanning confocal microscope (Olympus LEXT OLS4100, Tokyo, Japan) was employed to assess the surface roughness of the coatings via the acquisition of wear track 2D profiles and 3D microtopography images. More details about the experimental procedure can be found in our previous study [13].…”

“…It is noteworthy that the presence of high valence oxides decreases the corrosion rate and stabilizes the passivation film of the alloy [23]. Our previous work [13] has discussed the surface chemical states and the effect of high-valence oxide Ta 2 O 5 on the corrosion resistance of coating samples. In this study, the composition of the coating samples was the same, and all of them had the Ta outermost layer and possessed high purity, which resulted in similar XPS spectra.…”

“…The introduction of Ta into coatings via surface modification technologies is a reliable way to improve the surface and biological properties of biomedical metallic materials [8,10,[13][14][15]. For example, Hee et al [15] used a filtered cathodic vacuum arc deposition technique-the socalled bio-stable surface treatment-to prepare Ta and related nitride films on TC4 alloy, after which both the Ta and TaN films exhibited improvement in corrosion resistance.…”

Monolayer Ta and multilayer Ti/Zr/Ta and Zr/Ti/Ta coatings were prepared by magnetron sputtering on TC4 substrates to improve the surface friction and wear properties in a simulated body fluid (SBF) environment and an atmospheric environment. Optical microscopy, scanning electron microscopy, laser scanning confocal microscopy and nano scratch testing were employed to establish the structure-property-environment relationships. By controlling the preparation parameters, the outermost layer of all three samples was Ta coating, and the total coating thickness of each sample was about 3 μm. Friction and wear testing revealed that, compared to bare TC4 substrate, and multilayer Ti/Zr/Ta and Zr/Ti/Ta coatings, the monolayer Ta possessed the lowest friction coefficient as well as the minimum wear rate (i.e., calculation result of the wear track width and wear depth). This was mainly attributed to excellent adhesion strength, a particular structure and solid lubrication of the monolayer coating. The same coating sample exhibited a stronger wear resistance in the SBF environment than in the atmospheric environment. Furthermore, the wear behaviors and mechanisms of various coatings under different experimental environments are also discussed.

“…However, tantalum nitride has recently attracted great interest as a protective coating due to its excellent properties such as good wear and corrosion resistance, super hardness, high strength and toughness (even at high temperatures), high thermal stability, and great thermal conductivity [4,[11][12][13]. These properties position this material as a great candidate for different applications such as diffusion barriers, an application in which it has achieved a great reputation [14,15], silicon-based integrated circuits, high-performance microprocessors and in a wide variety of biomedical applications, showing that these coatings have better histocompatibility and hemocompatibility than traditionally used biomedical alloys [16,17]. Additionally, the superconductor TaN has been shown to be a much better candidate than niobium nitride (NbN) for the detection of single photons [15] due to its smaller space and lower density of states.…”

Growth Mechanisms of TaN Thin Films Produced by DC Magnetron Sputtering on 304 Steel Substrates and Their Influence on the Corrosion Resistance

et al. 2022

In this work, thin films of TaN were synthesized on 304 steel substrates using the reactive DC sputtering technique from a tantalum target in a nitrogen/argon atmosphere. All synthesis parameters such as gas ratio, pressure, gas flow, and substrate distance, among others, were fixed except the applied power of the source for different deposited coatings. The effect of the target power on the formation of the resulting phases and the microstructural and morphological characteristics was studied using XRD and AFM techniques, respectively, in order to understand the growth mechanisms. Phase, line profile, texture, and residual stress analysis were carried out from the X-ray diffraction patterns obtained. Atomic force microscopy analysis allowed us to obtain values for surface grain size and roughness which were related to growth mechanisms in accordance with XRD results. Results obtained showed a strong correlation between the growth energy with the crystallinity of the samples and the formation of the possible phases since the increase in the growth power caused the samples to evolve from an amorphous structure to a cubic monocrystalline structure. For all produced samples, the δ-TaN phase was observed despite the low N2 content used in the process (since for low N2 content it was expected to be possible to obtain films with α-Ta or hexagonal ε-TaN crystalline structure). In order to determine the corrosion resistance of the coatings, electrochemical impedance spectroscopy and polarization resistance were employed in the Tafel region. The results obtained through this evaluation showed a direct relationship between the power used and the improvement of the properties against corrosion for specific grain size values.
