FRICTION STIR WELDING OF ALUMINUM-LITHIUM ALLOY V-1469-T

An examination of welded joints of aluminum-lithium alloy V-1469-Т sheets made by friction stir welding (FSW) was carried out. The X-ray inspection showed the absence of unacceptable defects along the entire length of the weld. The mechanical characteristics tests of welded joints showed that the strength level of FSW joints was 0.85 of the base metal strength with satisfactory ductility. Transmission electron microscopy allowed to define the strength-ening phase distribution in welded joint special zones.

Keywords: friction stir welding, regression model, aluminum-lithium alloy V-1469-T, mechanical properties, transmission electron microscopy (TEM).

RESEARCH OF STRENGTH PROPERTIES OF HEAT-RESISTANT FIBERGLASS HONEYCOMBS FOR CONSTRUCTION OF THE AERODYNAMIC SCREEN

This paper presents the results of researches of influence of a tilt angle of load application on strength properties of polyimide fiberglass honeycomb fillers of the SSP-7-4,2 brand. During this work it has been determined that change of indicators of compression and shear strengths of honeycombs depends both on the tilt angle, and on the direction of load application. It is shown that it is necessary to consider strength indicators of fiberglass honeycomb fillers depending on the direction of load application, both during operation and production.

Keywords: honeycombs, fiberglass honeycomb filler, polyimide resin, compression strength, shear strength.

NEW TECHNOLOGY FOR PRODUCTION OF ELECTROPHORETIC COATINGS ON THE PARTS OF A HELICOPTER OPERATING IN FRETTING-CORRОSION CONDITIONS

A new technology for producing an anticorrosion coating with a simultaneous antifriction effect is described, developed by the D. Mendeleev University of Chemical Technology of Russian and implemented at PJSC «Rostvertol» in 2018. It is based on the process of obtaining coatings by the method of cathode electrodeposition of water-borne polymer electrolytes, which are epoxy-amine adducts modified by isocyanines. The composition is modified by PTFE aqueous dispersion. A new equipment has been designed and manufactured, thus making it possible to obtain coatings by the method of cathode electrodeposition without the working solution.

Keywords: electrophoresis, cathode electrodeposition, polymer coating, helicopter parts, coating production equipment.

CLIMATIC FIELD TESTS OF SIAL TYPE METAL-POLYMER COMPOSITION MATERIALS IN MARINE CLIMATE

The article presents key approaches to the performance of the climatic tests of SIAL type metal polymer composite materials. The characteristic features of a multi-layer structure of the material were taken into account during the use of the samples with artificial starved spots which provide direct contact with the aggressive atmosphere of the coastal zone. There are given the results of a comprehensive assessment of the climatic resistance of the SIAL-3-1 material consisting of thin sheets of Al–Li alloy and fiberglass layers  in tests with regulated damages in the form of a starved spots, in the deformed state when a bending load is applied alongside with an assessment of the persistence of properties when tested for the low-cycle fatigue, as well as the results of the evaluation of moisture absorption by the layers of fiberglass in a hybrid material.

Keywords: corrosion, aging, metal-polymer composite materials, SIAL, full-scale climatic tests.

EXPERIMENTAL RESEARCH OF «FIBER–MATRIX» ADHESION STRENGTH IN CARBON FIBER EPOXY/POLYSULPHONE COMPOSITE

 

The paper proposes a method for determining the fiber-matrix adhesion strength by pushing-out the fibers by a nanoindenter (push-out test). There are given the results of experimental determination of this characteristic for carbon fiber epoxy/polysulphone composites  based on two brands of high-strength fibers, differing in diameter, cross-sectional shape and surface morphology. The correctness of the push-out process was controlled by the microscopy technique. The obtained values of adhesive strength can be considered as constants of polymer-fiber systems in the initial state.

 

Keywords: fiber composite, polymer composite material, adhesion, interface, interphase, boundary interaction, indentation, push-out test.

THEORETICAL ASPECTS WHEN CREATING ELECTRONIC REFERENCE X-RAY IMAGES CONTAINING QUANTITATIVE INFORMATION

 

The article presents the results of theoretical researches of creation of a catalog of reference digital images of porosity of silumin group aluminum alloys similar to the reference radiographic pictures which radiologists use when grading castings  by the porosity points . There is a five-point scale of porosity which is unambiguously defined by a thin section and drawing in the radiographic image. Each point of porosity corresponds to certain strength characteristics of an alloy. Creation and copying of catalogs of reference X-ray patterns is a labor-intensive and costly process therefore catalogs of porosity images on the electronic data medium, is a radical solution of this problem.

Keywords: porosity, reference sample, reference X-ray pattern, X-ray scale of porosity, radiographic image, digital image.
