  • Climatic tests according to resistance of materials to conditions of sea Arctic and Subarctic climates
    The study of climate resistance of non-metallic polymer materials for complex technical systems and structures used in the cold climate of the Arctic zone, is an important issue in the selection and development of the material. The materials should have the persistence of physical and mechanical properties not only in conditions of low temperatures and temperature changes, but to be resistant to high humidity and the influence of maritime climate. As part of the research climate resistance of materials for Arctic operation conditions for the grant program of the Russian Science Foundation (рroject №14-33-00032) has developed the technique of assessment of climatic resistance of non-metallic materials for storage and operation in the area of the Arctic and subarctic climates (MM1.595-20-470–2015). The technique allows researching the influence of the alleged climate of storage and operation factors on the structure changes and strength properties of the materials. And also can be used
    Keywords: climatic tests, non-metallic polymeric materials, Arctic climate.

  • The study of the corrosion of metals in tropical marine waters
    Method multisubstrate testing (MST) investigated the activity of biofilm on the samples of carbon steel after exposure in the Dam Bay of the South China sea. The close correlation between the corrosion losses of St. 3 and aktivity. The activity of biofilm on the surface of the steel plates increased with increasing time of exposure in the sea. Confirmed the accuracy and versatility of the method of MST in characterizing biofilms of marine origin.
    Keywords: corrosion losses, the activity of biofilm, the method of MST.

  • FUNCTIONAL HYBRID ANTICORROSIVE SYSTEMS WITH ANTIDEGRADATION AND SELF-DIAGNOSTIC CHARACTERISTICS
    The experience of creating and studying the properties of sandwich systems «epoxy-polyelectrolyte-inorganic counter-ion – modifier/epoxide-carbon filler» was generalized. It has been shown that due to the variable nature of the polyelectrolyte and the modifier been introduced into the polymeric binder may provide protective materials having variable antidegradation and self-diagnostic functions. These functions manifest themselves of speed reduction of underfilm corrosion of metal surfaces from the aging of the coating and variable of electrical resistivity obtained anti-corrosion systems at the loss of their hydroinsulating properties.
    Keywords: variable resistivity, intelligent anticorosive protective materials, the system «polymer-polyelectrolyte».

  • Features of receiving high-temperature oxide fiber
    Ceramic oxide fibers are widely used currently in many industries as a high-temperature heat-shielding and heat-insulating materials and also as components of composite materials with metallic and ceramic matrices. Oxide fibers produced by sol-gel technology, followed by high temperature heat treatment. Uncontrolled grain growth of oxide fibers at elevated temperatures reduces its mechanical strength. In this paper, the characteristics of high temperature oxide fibers are considered and the effect of heat treatment on the crystalline structure of the fiber is studied.
    Keywords: ceramic oxide fibers, mechanical strength, crystal structure, composite materials, heat treatment.
