    THERMAL BARRIER COATINGS: CURRENT STATUS, SEARCH, AND ANALYSIS
    (1068-1302/18/0102-0082 2018 Springer Science+Business Media, LLC, 2018) S. M. Lakiza; M. I. Grechanyuk; O. K. Ruban; V. P. Redko; M. S. Glabay; O. B. Myloserdov; O. V. Dudnik; S. V. Prokhorenko
    The principles for selecting materials to be used as thermal barrier coatings (TBCs) are presented. The advantages and disadvantages of new methods for TBC deposition are briefly described. After measurement of the thermal conductivity and thermal expansion coefficient, it is required to ascertain that such materials do not interact with the thermally grown aluminum oxide and then to determine their strength, fracture toughness, hardness, and Young’s modulus. The thermal conductivity of TBC can be reduced by increasing its porosity and suppressing its sintering. The need for and drawbacks of multilayer coatings are shown. If TBC meets all the requirements, then TBC corrosion resistance to Na2SO4, V2O5, P2O5, sand, and volcanic ash in operation and ways to protect TBC against damage need to be determined. The prospects and areas for development of these techniques are outlined.

    MICROSTRUCTURAL DESIGN OF ZrO2–Y2O3–CeO2–Al2O3 MATERIALS
    (2011) E. V. Dudnik; A. V. Shevchenko; A. K. Ruban; V. P. Red’ko; L. M. Lopato
    It is shown that microstructural design of ZrO2–Y2O3–CeO2–Al2O3 ceramics is based on interrelated processes in the synthesis of starting powders and their formation and sintering. Hydrothermal nanocrystalline powders are examined to establish the formation of self-reinforced and multilayer composites with high strength and bioinert implants of femoral heads resistant to ageing processes in the human body. The results serve as a scientific basis for microstructure design of fine-grained ZrO2-based composites in the ZrO2–Y2O3–CeO2–Al2O3 system with high strength and other properties.
