A study of spark plasma sintered Ti6Al7Nb alloy reinforced with yttria stabilized zirconia (YSZ) has been carried out to assess the biocorrosion response in Hank's solution. The results indicate that microstructural changes resulting from YSZ addition were considerably different pure Ti6Al7Nb. All + composites showed a higher Vickers microhardness value 10%YSZ exhibiting most enhanced hardness ...

Given the need to process anodes and composites based on nano-YSZ in reducing or air containing additional CO2 atmospheres for fabrication of solid oxide fuel cells (SOFCs), electrolysis (SOECs), we have studied effect exposure CO+N2/H2 CO2+air mixtures during sintering YSZ green pellets, prepared from commercial nanopowders, their structure, microstructure, chemical composition electrical prop...

CO2 and/or H2O were reduced to CO/H2 in micro-tubular solid oxide electrolysers with yttria-stabilized zirconia (YSZ) electrolyte, Ni-YSZ cermet cathode and strontium(II)-doped lanthanum manganite (LSM) oxygen-evolving anode. At 822 C, the kinetics of CO2 reduction were slower (ca. 0.49 A cm 2 at 1.8 V) than H2O reduction or co-reduction of CO2 and H2O, which were comparable (ca. 0.83 to 0.77 A...

conventional and nanostructured ysz coatings were deposited on the in-738 ni super alloy by the atmospheric plasma spray technique. the oxidation was measured at 1100°c in an atmospheric electrical furnace. according to the experimental results the nanostructured coatings showed a better oxidation resistance than the conventional ones. the improved oxidation resistance of the nanocoating could ...

Synthesis of YSZ nanopowder by alkoxide sol-gel method, through two different hydrolysis routes, one under careful control by using acetyacetone as ligand, and the other through basic hydrolysis, was investigated. The synthesized powders were characterized by various analytical techniques such as, XRD, STA, PSA, BET, SEM, and TEM. The results showed that, the YSZ powders prepared through the ba...
