EFFECT OF MUTUAL STABILIZATION OF POLYETHERETHERKETONE AND THERMOTROPIC LIQUID CRYSTAL POLYMERS IN POLYMER COMPOSITES BASED ON THEN FOR 3D PRINTING

The effects of mutual diffusion, expressed in the nature of the temperature dependences of viscosity and other thermophysical characteristics of the melt of a filament based on polyetheretherketone (PEEK) and liquid crystal polymers (LCP), including depending on the printing speed and the content of the LC phase, are considered and substantiated. Relaxation transitions inside the fiber itself and the film obtained from it by 3D printing are characterized. It has been shown that the introduction of LCP into a thermoplastic matrix based on PEEK can stabilize the viscous behavior of the melt of a thread during its solidification.

RESEARCH OF CORROSION RESISTANCE OF THE HYBRID LAYERED METAL POLYMERIC MATERIALS

Complex research of corrosion resistance of the hybrid layered metal polymer material «aluminum–organoplastiс» has been conducted according to the techniques accepted for different classes of materials: metals, polymer composites, adhesive compounds. It is established that the hybrid material has corrosion on surface and at the ends of the samples such as a metal alloy has. An there is also a number of features which are caused by layered structure of the metal composite, the permeability of layers of organoplastic to moisture and electrolytes.

APPLICATION TRENDS OF HIGH TEMPERATURE REFRACTORY OXIDES FOR SOLID OXIDES FUEL CELLS

Solid oxide fuel cells attract the attention of developers due to their high energy efficiency, environmental friendliness and a wide variety of types of fuel used. The publication is devoted to the current state of the issue in the field of materials development for solid oxide fuel cells (SOFC). Ceramic oxide materials used for the anode, cathode and electrode of fuel cells are considered. It is shown that interest in solid oxide fuel cells will steadily grow, while small-sized SOFC up to nanoelements will have a special perspective.

POSSIBILITY OF USING LAYER-BY-LAYER DEPOSITION TECHNOLOGY (FDM) TO PRODUCE CERAMIC PRODUCTS

When producing ceramic products with complex shapes, traditional methods cannot compete with additive manufacturing methods. This is due to both the complexity of manufacturing molds and injection molds, and the need for subsequent mechanical processing, which significantly complicates and increases the cost of the process of obtaining a product. This article discusses the layer-by-layer deposition technology (FDM). Its main advantages and disadvantages are given. The results of producing ceramic polymer filament and products made from it using FDM technology are presented.

THERMAL INDICATOR MATERIALS AND THEIR APPLICATION

Thermal indicators include substances that have the ability to sharply change their color at a certain temperature, called the transition temperature. These materials are of significant interest to researchers and manufacturers as they have potential for many technological applications such as aerospace, functional coatings, military applications, printing technologies, «smart» windows, temperature sensors, etc. The nomenclature and variety of thermal indicator substances are constantly evolving, as evidenced by the annual increase in scientific and technical literature publications on this topic.

THE EFFECT OF THE OPERATING MODE OF THE NEGATIVE POTENTIAL SOURCE DURING GRADIENT DEPOSITION OF THE PROTECTIVE COATING ON THE RESISTANCE TO SULFIDE OXIDE CORROSION AND SCALE RESISTANCE

The results of a study of the effect of a constant or pulse mode of operation of a negative potential inverter during gradient deposition of the protective coating of the composition SDP-1+VSDP-13 on resistance to sulfide oxide corrosion (SOC) at a temperature of 950 °С based on 30 cycles and scale resistance at a temperature of 1100 °Сbased on 200 hours are presented. It was found that the increased resistance of the «alloy–coating composition» to the effects of SOC and scale resistance are shown by coatings applied under constant operation of the inverter and with an increased potential of 70 V.

DETERMINATION OF PLATINUM GROUP ELEMENTS IN NICKEL ALLOYS BY INDUCTIVELY COUPLED PLASMA MASS SPECTROMETRY METHOD

The work determined the impurities of platinum group metals (Ru, Rh, Pd, Os, Ir, Pt) and gold in complex-alloyed nickel alloys using inductively coupled plasma mass spectrometry. The method for dissolving a sample and preparing it for analysis is presented. Spectral interferences are eliminated using a reaction-collision cell and a mathematical correction method. The accuracy of the results was confirmed by comparative analysis with data obtained using high-resolution mass spectrometry with a glow discharge.

METHODOLOGICAL FEATURES OF STUDYING THE DENSITY OF METAL POWDER COMPOSITIONS AT HIGH TEMPERATURE

This paper proposes an approach to estimating the density of solid materials at elevated temperatures, based on measuring the temperature coefficient of linear expansion. Measurements of metal powder compositions of alloys EP741NP, VZh178P and VZh159 were carried out. The temperature dependences of the density of the powders under study were established in the temperature range from 200 to 1100 ºС and the correctness of the results obtained was assessed. The features of the experiment are shown, and the advantages and disadvantages of the proposed measurement method are considered.
