REPAIR OF NOZZLE BLADES MADE OF HEAT-RESISTANT NICKEL ALLOY ZhS6U

An overview of traditional methods for cleaning the surface of gas turbine engine (GTE) blades from products of gas corrosion and spent coating, methods for restoring the structure and properties of the material of blades using hot isostatic pressing and heat treatment, as well as methods for applying coatings on the inner and outer surfaces of the blades is presented. The main disadvantages of these methods are described, taking into account which the state-of-the-art technology for repairing gas-turbine engine nozzle blades made of ZhS6U alloy has been developed in FSUE «VIAM», which ensures an increase in their resource and a reduction in repair costs.

In FSUE «VNIIOFI» tests of CRM material were carried out in order to approve their type, as well as metrological examination. Conclusions were drawn up on checking the results of CRM testing for the composition of the indicated alloys and certificates of type approval of reference materials were issued. CRM sets of the approved type of state standard samples of high-strength magnesium alloys of VML20 and VMD16 grades have a relative error of the certified values of the mass fraction of elements in the range from 0.5 to 5% (by weight) no more than 5% rel.

ORGANOPLASTICS BASED ON HEAT-RESISTANT POLYMER FIBERS AND MATRICES

The properties of heat-resistant polymer fibers (Arimid, PFBT) and samples of organoplastics based on them have been investigated. It has been established that polyimide and polybenzazole fibers can be used as a reinforcing filler to create organoplastics at operating temperatures up to 350‒400 °C. The level of retention of the elastic modulus in bending of organoplastics based on PFBT fiber and IP-5 heterocyclic binder is 90 %. Heat-resistant organoplastics are promising for use in the aerospace industry and mechanical engineering.

INVESTIGATION OF THE EFFECT OF OXIDE ADDITIVES ON THE PROPERTIES OF HEAT-RESISTANT GLASS-CRYSTAL COATING

Experimental compositions of coatings based on SiO₂–Al₂O₃–MgO matrix glass and modifying additives are considered. A number of refractory metal oxides were selected as modifying additives. The influence of these additives on the properties of the coating melt, such as the spreadability and the wetting edge angle, as well as the oxidability of the resulting compositions, is studied. It was found that the experimental coating modified with aluminum oxide has the best protective properties. The introduction of modifying additives in quantities of more than 5 % is considered inappropriate.

INVESTIGATION OF POLYMER COMPOSITE MATERIAL SAMPLES BY X-RAY COMPUTED TOMOGRAPHY AND PROCESSING OF TOMOGRAMS WITH THE IMAGE OF THE VOLUME FRACTION OF POROSITY

The question of the quality of samples made of polymer composite materials and its verification by x-ray computed tomography is considered. The capabilities of North Star Imaging X5000 tomograph were studied and the samples from PCM were examined for detection and evaluation of the porosity volume fraction. The factors influencing the accuracy of the estimation of the porosity volume fraction are investigated. Namely the size voxel, a filter material, quantity of projections. On the other hand, the size вокселя defines resolution of the digital image, the relation depends on a material of the applied filter a signal/noise, productivity of control worsens with growth of quantity of projections. The choice of optimum values of the listed parametres is necessary for satisfactory quality received tomographic images.

CARBON AND GLASS REINFORCED POLYMER BASED ON SOLVENT-FREE BINDERS RESISTANCE TO THE IMPACT OF A MODERATE COLD AND MODERATE WARM CLIMATE

In this work has been investigated the climatic resistance of carbon and fiberglass polymers for aviation purposes based on solvent-free binders VST-1208, VSE-1212, VSR-3M after 3 years of exposure of these materials in the moderate cold climate of Moscow and the moderate warm climate of Gelendzhik. The effect of destruction, post curing, plasticization of binders on the compressive and flexural strengths of carbon plastics VKU-27L, VKU-39, VKU-46 and fiberglass plastics VPS-47/7781, VPS-48/778 was determined using the methods of profilometry, moisture transfer and dynamic mechanical analysis. It is shown that while determining the state of PCM after climatic exposure, it is necessary to take into account the effects of the reversible plasticizing action of moisture. A comparison is made of the climatic resistance of the investigated materials.
