Mechanical behaviour of yttria- and ferric oxide-doped zirconia at different temperatures

Defect structure of yttria-stabilized zirconia and its influence on the ionic conductivity at elevated temperatures

The defect structure of cubic fluorite structured yttria-stabilized zirconia (ZrO2)12x(Y2O3)x has been investigated over the composition range 0.100(4)<x<0.241(10) and temperatures T(K) up to 2780~10! K, using single-crystal specimens. Analysis of neutron and x-ray diffraction data, including both Bragg and coherent diffuse scattering components, has identified three principal types of defects ...

WEAR REESISTANCE OF NANOSTRUCTURED AND CONVENTIONAL YTTRIA-STABILIZED ZIRCONIA COATINGS

Partially stabilized zirconia (PSZ) has been proven to be an excellent candidate as a thermal barrier coating (TBe) for hot sections in, for instance, heat or internal combustion engines and gas turbine parts. The main functions of these coatings are reducing heat losses, reducing fuel consumption, increasing efficiency, and extending durability and life. One of the main problems involved is we...

Effect of Water/Alkoxide Molar Ratio on the Synthesis Process and Electrochemical Behavior of Yttria-doped Zirconia Sol-gel Films

The aim of this work is to synthesize and investigate the performance of yttria-doped zirconia solgel coatings in the chemical corrosion prevention of zircaloy-4 (zirconium alloy) in a 1 N H2SO4 environment. The influence of four different molar ratios of water to alkoxide, namely 1, 4, 12, and 20, on the coating quality and its corrosion prevention performance was investigated. Differential th...
