WAYS OF INCREASING CORROSION RESISTANCE OF SUPERALLOYS (review)

Ni-based superalloys are widely used in the aviation, energy and nuclear industries. They are used in conditions of high temperatures, stresses and corrosive medium, which is why the issue of oxidation resistance is actual. The article describes the results of recent studies aimed at increasing the corrosion resistance of high-temperature Ni-based alloys. Traditionally, the issue of increasing corrosion resistance is solved by a variation in the chemical composition. Elements such as aluminum and chromium contribute to the formation of a complex oxide film on the metal surface. This has a beneficial effect on the operational characteristics of the alloy. When analyzing the literature data, the results of studies carried out by the authors on intermetallic alloys were confirmed: doping of alloys with refractory elements such as Mo and Re has a negative effect on the corrosion resistance. Most actively carried out research work in the direction of additional alloying of materials with

OPTIMIZATION OF ARTIFICIAL AGING OF FORGED AND ROLLED SEMI-FINISHED PRODUCTS FROM HEAT-RESISTANT ALUMINUM ALLOY AK4-1h.

The article presents the results of the study of the effect of aging regimes on the mechanical and corrosion properties of semi-finished products from AK4-1 alloy - rolled plates from 12 to 60 mm thick and forgings 135 and 225 mm thick. The temperature of artificial aging was varied in the range 190–200C, the holding time varied from 5 hours to 22 hours. It was found that with an increase in the holding time from 5 to 18 hours at a temperature of 190 and 200°C, the temporary resistance and the yield strength of the plates is reduced by 10–30 MPa, and in the interval of exposures of 14–18 hours the relative elongation of the plates decreases, especially in the altitude direction . The influence of the temperature-time parameters of aging on the propensity of plates to delaminating and intergranular corrosion in the investigated interval of aging regimes has not been revealed. The study of forgings from the AK4-1h alloy aged at 190 and at 200°C showed that the temporary resistance (

PROPERTIES OF BINDER EDT-69N AND POLYMER COMPOSITES ON ITS BASIS

The binder EDT-69N is widely and efficiently used in industry as a part of different polymer composites. The article specifies the main types of materials, created on the basis of these binder, their compositions and application fields in the aviation industry. If it is necessary to obtain materials with improved properties, it is also recommended to modify the composition of the binder and its curing program. Evaluation of the influence of the filler type was carried out by comparing physico-chemical characteristics of the curing process of prepregs on the basis of the binder and the fillers used immediately after the preparation of the samples. For the analysis, thermal analysis methods (differential scanning calorimetry, differential thermal analysis (DTA), thermogravimetric analysis (TGA) and differential thermogravimetric analysis) and IR spectroscopy were used. Comparison of IR spectra of the binder before and after curing at different temperatures made it possible to reveal th

RESEARCH OF PECULIARITIES OF MECHANICAL DECOMPOSITION IN SYNTHESIS OF IN-SITU COMPOSITES BASED ON REFRACTORY METALS

The article describes the method of mechanical alloying as an alternative for obtaining high-temperature materials based on niobium, the obtaining of which by traditional methods (casting technologies) entails great difficulties. Particular attention was paid to the control of intermediate operations related to the process of mechanical alloying. The evolution of the microstructure, phase and granulometric compositions of composite powders (CP) of the Nb–Si–Ti system at various stages of mechanical doping is considered. It is established that the process of mechanical doping consists of two processes: the actual alloying process, which is controlled by the time of powder formation with the X-ray amorphous structure and the process of creating a fractional composition controlled by a histogram of powder distribution in size. The choice of the most effective method of quality control of alloying KP was made. This method is XRF, the criterion of which is the amorphization of the structu

SURFACE PREPARATION ALUMINUM ALLOY V-1469 BEFORE USE IN THE COMPOSITION OF LAYERED HYBRID MATERIAL

Despite the increased interest of designers to composite polymeric materials (PCM), aluminum alloys are the main structural material of the aviation industry. Particular attention is paid to aluminum-lithium alloys and hybrid materials based on them, such as SIAL, which are layered materials of a new generation. SIALs are layered hybrid metal-polymer materials, which consist of thin sheets of structural aluminum alloys and GRP based on adhesive melt-type binders and glass fiber fillers with different reinforcement structures. The article provides information on the preparation of the surface of the aluminum-lithium alloy V-1469, which was selected for use in SIAL for the manufacture of wing panel panels. In this paper, the issue of protecting such alloys from corrosion and giving their surfaces special properties, in particu-lar, ensuring good adhesion of epoxy adhesive binders, is considered. Various types of anodic oxidation of the surface of aluminum alloys for bonding are conside

FEATURES OF DESTRUCTION OF DETAILS OF FIXTURE FROM THE CONSTRUCTIONAL STEEL

Features of destruction of samples from steel 30ХГСА with galvanotermic coatings on the basis of zinc are analyzed. At formation of a break of the samples tested for grain-boundary brittle destruction, three areas differing on a structure are created. In a near surface zone under a sheeting the area of the maleficiated relief with destruction on the mechanism of a viscous cut is formed. Further the area with a rough relief in which it is possible to allocate a zone of the slowed-down destruction with brittle facets and a zone viscous dimple rupture is created. It is established that when testing for low-cycle fatigue samples from steel 30ХГСА with galvanotermic coatings the centers of destruction are risks or other defects on a steel surface under a covering. In an focal zone the fan-shaped relief is most often observed. In process of removal from the center of destruction fatigue plateaus and grooves are created. In break viscous poles are formed. Research of the destroyed axis made

HEAT-REFLECTIVE COATING FOR PROTECTION OF EXPANDABLE STRUCTURE ON AGAINST INFLUENCE OF THE HEAT TRANSFER RATE

Passenger evacuation in the event of a flight accident is often carried out using of inflatable life designs, and in the event of a fire it is important to save the air-tightness and efficiency of the life rafts. In defence of the membranous tissue materials, whereof inflatable life designs are manufacture, heat-reflecting enamel VE-72 is developed from influence of thermal radiation. Research has shown that the heat-reflecting coating of the VE-72 has high technical charac-teristics and also has proved the high efficiency of the heat-reflecting properties of the coating: the duration of the preset overpressure preservation of 20 kPa from exposure of an external heat current of 1,7 W/c2 is 15 minutes even with glue seams, which is 5 times higher than the requirements of the standard TSO-C69c and 3 times higher than the foreign equivalent of art. M-11673 (Air Cruisers Company, USA). Tests of materials on the preservation of leakage under the influence of radiant heat current were carr

TRIBOLOGICAL CHARACTERISTICS OF THE ALKYD COVERINGS FILLED WITH ABRASIVE FILLERS OF DIFFERENT SIZE

In article results of research of tribological properties of model systems of nonskid coatings based on one-component alkyd binding with abrasive fillers like sand and electrocorundum of different fractions was applied. Submitted data can be used when developing nonskid coatings which are actively applied, both in the aviation industry, and in other spheres of national economy. Intelligent approach to the nature and the size of the chosen filler will allow not only to improve considerably functionality of nonskid coating, but also to increase term of its operation. Values of friction coefficient, as one of the main characteristics of this type of coatings, are given. Observations concerning surface qualities and resistance to abrasion are showed. Definition of friction coefficient were carried out on the tribometer CETR UMT-3MT with use of drive of R33HE350 for reciprocating motion on the mode modeling the beginning of slipping of shoe sole on dry nonskid coating. It is shown that ex

CORROSION BEHAVIOR OF Al–Si–Mg ALLOY MADE BY SELECTIVE LASER MELTING METHOD

Selective laser melting (SLM) is a promising technology for complicated configuration details manufacture. Al-Si alloys are the most investigated alloys in selective laser melting manufacture at the time. A mechanical, corrosion and operational performance of SLM and as-cast details are deeply vary because cast structure stands in stark difference to SLM structure. In this article a corrosion behavior of synthesized and heat treated Al–Si–Mg alloy is shown. Also the results of general and intergranular corrosion are shown. The corrosion behavior of AlSi10Mg aluminum alloy with additives of Cu, Zr, Al–Si–Mg system Ce directly depends on structure of a material which in turn depends on manufacturing techniques and modes of thermal processing. In a cast condition the material shows the lowered corrosion resistance owing to formation of large dentritny structure in the course of crystallization. Development of corrosion processes in an alloy made by a SLS method, depends on quantity, the

RESEARCHING OF MECHANICAL PROPERTIES OF DEFORMED SEMI-FINISHED PRODUCTS OF VT23M AND VT43 ALLOYS, ASSESSMENT OF THEIR CLIMATIC STABILITY IN THE ARCTIC CLIMATE

The studies, showed, that the structure of the manufactured semi-finished products from the alloys VT23M and VT43 is typical for deformable semi-finished of (α+β) titanium alloys. It was noted that the average size of structural components of semi-finished products of VT43 alloy is smaller than that of VT23M semi-finished products. Tensile tests to determine the mechanical properties of samples from sheets and bars of VT23M and VT43 alloys were carried out at room temperature (20°C) and lowered (-60°C) temperatures. Since the sheets of the VT43 alloy were first obtained within the framework of this work, in order to evaluate the anisotropy of the mechanical properties, tensile tests at a temperature of +20°C were carried out in the longitudinal and transverse directions of hot rolling. It is shown that under the same production conditions for the of sheets from the investigated alloys, the alloy VT43 has a 9,6% higher strength, with an equal elongation. The comparison is given for th
