DAMPING PROPERTIES OF HYBRID LAYERED METAL-POLYMER MATERIALS BASED ON ALUMINUM, TITANIUM ALLOYS AND ORGANOPLASTICS LAYERS

The damping characteristics of hybrid layered materials of the class «aluminum–organoplastics» and «titanium–organoplastics» based on metal sheets and layers of aramid organoplastics are studied. It is shown that the level of damping properties of hybrid layered materials is higher than that of the initial alloys and depends on the volume content of organoplastics, the location of organoplastics layers relative to metal layers, as well as on the reinforcement scheme. Hybrid layered materials are promising materials for the manufacture of high-speed aircraft structures operating under high vibroacoustic loads.

EVALUATION OF THE EFFECTIVENESS OF THE FIRE RETARDANTS, PROMISING FOR THE CREATION OF NEW POLYMER COMPOSITE MATERIALS INTENDED FOR AVIATION TECHNIQUES

Studies have been carried out on the effectiveness of the action of two types of fire retardants – graphene and an organic phosphorus-containing compound DOPO-THPO, introduced into an epoxy resin. The amount of fire retardants introduced was 0; 2 and 4% of the amount of epoxy resin. The efficiency was assessed by the oxygen index method (LOI). It was shown that for this epoxy resin, the introduction of graphene provided an increase in the oxygen index from 21 to 27%, and the introduction of the phosphorus-containing fire retardant DOPO-THPO – from 21 to 23%. With the simultaneous introduction of graphene (3%) and DOPO-THPO (1%), it was possible to achieve an increase in the oxygen index up to 28%.

INVESTIGATION OF THE STRENGTH CHARACTERISTICS DISPERSION-STRENGTHENED METAL-CERAMIC COMPOSITE MATERIAL VKM22

In many industries, such as mechanical engineering and aerospace, traditional alloys are being replaced by metal matrix composites (MCM). Compared to unreinforced alloys, MCM is characterized by increased strength and rigidity combined with low density. To calculate the resource of nodes for the safe and reliable operation of new equipment, it is necessary to have a set of calculated values of the MCM strength characteristics, including the characteristics of short-term and long-term strength, low-cycle (LCF) and high-cycle (HCF) fatigue. The work is devoted to the study of the characteristics of short-term and long-term strength, LCF and MCF fatigue of dispersion-strengthened MKM grade VKM22.

THE INFLUENCE OF INTERSTITIAL IMPURITIES IN THE Zr–Y TARGET ALLOYS ON THE HEAT RESISTING CERAMIC COATING QUALITY

The influence of interstitial impurities in the Zr–Y target alloys (manufactured by two different techniques) on the quality of thermal barrier ceramic layers of heat resisting coating are studied in this work. The heat resisting ceramic coating manufactured in the UOKS-2 devices by magnetron medium-feculence plasma–chemical deposition on the surface of components that are used at the high temperatures (above 1150 °C). It was found that when the content of interstitial impurities in the target alloy is more than 0,1% (1000 ppm), the rate of the coating process decreases and has to be maintained by increasing the energy of argon ions. This leads to overheating of the target alloy and the surface of the parts (substrate) which impairs the adhesion of the deposited atoms.

IMPROVING OF FRETTING RESISTANCE INTERMETALLIC Ti2AlNb ALLOY

The results of research on improving the fretting resistance of a titanium alloy made of orthorhombic titanium aluminide Ti₂AlNb by forming a coating consisting of a barrier and an outer layer on the surface using an industrial vacuum-arc installation MAP-3 are presented. The dependences of the total wear and the coefficient of friction of samples made of Ti₂AlNb alloy with and without coating in combination with a counterbody made of high-strength welded dispersed-hardening alloy during fretting damage tests at room (20 °C) and elevated (700 °C) temperatures are established. The kinetics of oxygen saturation of the surface of samples made of Ti₂AlNb alloy with and without coating at the operating temperature of the alloy based on 200 h is shown. The phase and elemental compositions of the fretting-resistant coating after high-temperature exposure are investigated.

SECONDARY PROCESSING OF CAST TUBE CATHODES WHEN OBTAINING A METAL POWDER COMPOSITION FOR THE GAS-THERMAL SPRAY OF COATINGS

The paper presents the results of structural studies of metal-powder compositions (MPC) from the VSDP-3 alloy, as well as heat-resistant atmospheric-plasma powder coatings, developed at the FSUE «VIAM». As blanks for sputtering the MPC, standard charge blanks and exhausted resource cast tube cathodes for ion-plasma deposition were used. It was found that MPC obtained by sputtering cathodes and coatings deposited by sputtering these MPC are not inferior in properties to standard MPC and coatings. At the same time, the cost of such MPC and coatings can be 20–40% lower.

A STUDY OF THE USE OF COMBINED ANODIC DISSOLUTION OF ALUMINUM ALLOYS WITH NOT HIGH SENSIBILITY TO IGC EVIDENCE FROM ALLOY OF Al–Li–Cu SYSTEM WITH THE PURPOSE OF PREDICTING LOSS OF MECHANICAL PROPERTIES AT ATMOSPHERIC CORROSION

The article presents data on combined anodic dissolution of aluminum alloy of Al–Li–Cu system with not high sensibility to intergranular corrosion, consisting in sequential dissolution in two different solutions, with different modes – the ratio of the specific amount of electricity. The obtained corrosion deteriorations were evaluated by optical and confocal microscopy, the dependences of mass loss, the depth of pitting and intergranular corrosion, as well as changes in the tensile strength of the specific amount of electricity for different modes were determined. As a result of the analysis of the obtained data, models for predicting the loss of tensile strength from the value of the specific amount of electricity (or mass loss) in atmospheric corrosion are proposed.
