Investigation of coating CLAM steel substrates with erbium oxide by a magnetron sputtering method

Recent decades jewelry manufacturers put into practice using of non-precious alloys in order to decrease the production costs. Nevertheless, the large number of customers has allergic (sensitizing) body reaction on jewelries. Applying of non-sensitizing coating is able to decrease negative influence of jewelry material on human body. One of the biologically inert materials toward to human body tissues is zirconium. In the present work we examined the zirconium-based coatings applied by magnetron sputtering. Eleven coating regimes of AISI 430 steel substrates by zirconium oxynitride were investigated. Coatings corrosion test in Hank’s solution, microhardness measurements, color performance in CIE 1976 L*a*b* and RGB color spaces were carried out. The coating width was 0.4–1.2 μm. It was established that coatings have microhardness 2.5–3.0 GPa and can simulate jewelries colors. Using energy dispersive X-ray spectroscopy, it was evaluated that coatings consist of Zr, N and O. We select the sputtering regimes which provides metallic type coatings with the high optical reflectivity in the energy range near the infrared part of spectrum (<1.7 eV) and has golden color with a high lightness. It was experimentally proved that coatings are not corroding in Hank’s solution. The allergy patch test of jewelry with zirconium oxynitride coating demonstrate a good result on respondents with sensitizing reaction to non-precious alloys jewelry. The obtained results allow us to recommend the application of a zirconium-based coating magnetron sputtering in manufacturing of the non-precious alloys jewelry.

In the present work, nanostructured tungsten nitride (WN) thin films were deposited by RF reactive magnetron sputtering technique in a mixture of N2 and Argon atmosphere and its microstructure and mechanical properties were investigated. The Argon pressure was kept constant at 20 sccm, while the N2 partial pressures were varied (3%, 5%, 10% and 15%). The WN thin films are deposited on SS304 stainless steel substrates at a temperature of 500 °C. The microstructural property was analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM) and mechanical properties were evaluated by nanoindentation technique. The XRD studies indicated the formation of different phases as a function of nitrogen content. The hardness and the young’s modulus values were in the range 27–39 GPa and 239–280 GPa, respectively. The high hardness values correspond to the coatings with the low nitrogen content and vice-versa. The mechanical properties of the tungsten nitride coatings were strongly influenced by the microstructure.

ZrN thin films were successfully deposited by DC magnetron sputtering on die steel substrates. The objective of this study was to investigate heat treatment on the microstructure, morphology, nanohardness properties determined by X-ray diffraction, field-emission scanning electron microscope (FE-SEM), nanoindentation, and pin-on-disk, respectively. The XRD result shows that ZrN has intensity of (111) and (200) peak after 400 °C for 1 h at lower nitrogen flow rates. The surface of coatings revealed smaller grains and smooth surface under heat treatment. ZrN coatings consisted of lower nitrogen flow rate had much lower friction coefficient, better mechanical properties by annealing treatment process.

Crn Coatings

Mechanical and tribological properties of CrN coatings grown on steel substrates AISI 304 and AISI 4140 using the magnetron sputtering technique were analyzed. Coatings were grown at two pressures of work, 0.4 and 4.0 Pa. The films grown on AISI 304 at a pressure of work of 0.4 showed the highest hardness because it presented a larger grain size and lower roughness. For CrN synthesized at 0.4 Pa, the surface damage was lower during the tribological test. Adherence studies were also carried out, obtaining <em>Lc</em>1 and <em>Lc</em>2 for coatings produced at both pressures and on both substrates. Better adherence behavior was observed for films grown at a low pressure because these films were thicker (~890 nm).

Diamond-like carbon is one of the most studied and used solid lubricants on the market. Despite this large use and its outstanding mechanical and tribological properties, there are still some unclear aspects related to its self-lubricant properties, and some drawbacks in the deposition methods. We deposited “soft” DLC films on Si(100), iron, and stainless steel substrates by PVD magnetron sputtering technique with a Cr/CrN adhesive interlayer. The DLC films were characterized from a chemical, mechanical, and tribological point of view. Our aim was to connect the coating chemical and mechanical characteristics to the different conditions used for the deposition, such as discharge power and substrate–target distance. We found a stronger sp3 dependence on the discharge power for DLC deposited closer to the target. The tribological results did not depend on the chosen substrate–target distance, but rather on the hardness of the substrate. This could be ascribed to the better mechanical coupling of soft DLC films on harder substrates.

Different Mo content of ternary Cr-Mo-N films were deposited on steel substrates using closed-field unbalanced magnetron sputtering technique using Cr target and Mo target in N2/Ar gaseous mixture. The composition, structure, surface morphology and valence states of ternary CrMoN films were tested by EDS, XRD, SEM and XPS respectively. The experimental results showed that the preferential growth orientation of CrMoN films was changed from CrN (220) to (200) after the addition of Mo element. The diffraction peak shifted leftwards as a function of Mo content, The synthesized CrMoN coatings formed a substitutional solid solution of (Cr,Mo)N where larger Mo atoms replaced Cr in CrN crystal. The mechanical property experiments were carried out on the nanotest 600 hardness-testing device. The hardness of CrMoN films enhanced for the synergistic effect of CrN and MoN hard phases
