Abstract:

Metallic Cr and multilayer CrN/Cr coatings with a thickness of 2.5 µm were deposited onto E110 alloy by magnetron sputtering. Oxidation tests in air were performed at 1100 °C for 10–40 min. The gravimetric measurements showed better protective properties of multilayer CrN/Cr coatings in comparison with metallic Cr coating. Multilayer coating prevented fast Cr–Zr inter-diffusion by the formation of a ZrN layer beneath the coating. The appearance of ZrN is caused by interaction with nitrogen formed from the decomposition of CrN to Cr2N phases. Optical microscopy revealed a residual Cr layer for

The XRD analysis revealed that the coatings were composed of TiN, TiNC and α-Al2O3 phases. After exposure to supercritical water, the surface morphology of the coatings was still dense and kept integrity.

The adhesive wear played a predominant role under the condition of a larger normal load and lower velocity, leading to the formation of a third body layer composed of compressed and lubricating oxides. As a result, the wear rate of the coating tested at 20 N reduced by 23% of that tested at 5 N. Instead,

An innovative energy-saving technology for producing block foam glass with a protective decorative coating has been developed, including the preliminary application of an intermediate heat resistant coating followed by the application of the main coating and the plasma jet melting. The optimal composition of the intermediate heat resistant coating, its preparation technology and laying on the front surface of the foam glass block are determined. It is shown that the main factor shaping the quality of the foam glass insulating block with a protective decorative coating is the speed of the plasm

Abstract:

The glass molding process provides great potential for mass production of precise glass optical components at low cost. The key issue for achieving a low production cost is to extend the service life of the expensive mold inserts. The precious metal based alloy is one of the coating materials for the molds which provides excellent glass anti-sticking results. However, the inter-diffusion between the WC/Co mold materials and precious metal coatings will deteriorate the coatings which needs to be resolved. It is essentially to deposit an interlayer as the diffusion barrier to improve the inter-d

Magnetron sputtering was used to obtain single-layer MoSi2, MoSiB and multilayer MoSiB/SiBC coatings. Coating structures were studied using X-ray phase analysis, scanning electron microscopy and glow discharge optical emission spectroscopy. Mechanical properties of the coatings were determined by nanoindentation. The coatings were tested for oxidation resistance and thermal stability at temperatures between 600 °С and 1200 °С. It was found that single-layer MoSiB coatings have a hardness of 27 GPa, elasticity modulus of 390 GPa and elastic recovery of 48 % and exhibit short-term oxidation resi

In this work, multilayer gradient coatings obtained by detonation spraying were studied. To obtain a multilayer gradient coating by detonation spraying, two modes with different numbers of shots of NiCrAlY and YSZ were developed. The presented results demonstrate the effectiveness of creating a gradient structure in coatings, ensuring a smooth transition from metal to ceramic materials. Morphological analysis of the coatings confirmed a layered gradient structure, consisting of a lower metallic (NiCrAlY) layer and an upper ceramic (YSZ) layer.

A dissolvable material used in oil/gas field was introduced. The corrosion property of the dissolvable material was characterized by using immersion method and scanning electron microscope. The dissolvable material could quickly react with KCl solution, and the reaction rate improved with the increase of the temperature. In some cases, the downhole tools made by dissolvable materials should not react with well fluid in a short term. Then a protective multilayer coating was fabricated on the material surface.

Enhanced corrosion efficiency of low-carbon steel was achieved by newly developed hybrid multilayers, composed of low-carbon steel coated with an electrodeposited zinc sublayer (1 µm), a chitosan (CS) middle layer and ZrO2 coating by the sol–gel method (top-layer). The middle chitosan layer was obtained by dipping galvanized steel substrate in 3% tartatic acid water solution of medium molecular-weight chitosan, composed of β-(1–4)-linked D-glucosamine and N-acetyl-D-glucosamine with a deacetylation degree of about 75–85% (CS).

A rapid path for element diffusion was provided by the defects, which were promoted by stress, expansion, and gas volatilization. Both the TiN a
