ZrO<Subscript>2</Subscript> coatings on SiC fibers

Zirconia coatings have been produced on Hi-Nicalon fibers via pyrolysis of zirconium oxalates extracted into amine-benzene solutions. X-ray diffraction and electron probe x-ray microanalysis results demonstrate that the pyrolysis of extracts is a viable approach to producing thin zirconia coatings on coreless silicon carbide fibers and that further research is needed to optimize the microstructure of zirconia coatings.     

Eu2O3/SiO2 nanocomposites obtained by extraction pyrolysis

The conditions of the formation of nanosized Eu₂O₃/SiO₂ composites were studied. Amorphous silicon dioxide was coated with europium oxide by extraction pyrolysis. The resulting samples were studied by X-ray phase analysis and atomic force microscopy. The Eu₂O₃/SiO₂ composites were tested as catalysts of CO conversion.

Plasma-electrolytic formation of Ta-containing oxide coatings on titanium. Their composition and properties

Coatings with a thickness of 2–18 μm that contain up to 20 at % tantalum and Ta₂O₅ oxide phase are formed in an aqueous NH₄[TaF₆]-containing electrolyte for 2 min. The coatings are pierced with pores with a size of from 0.5 to 2 μm. The number of pores in the coatings can be decreased by additionally applying a Ta-containing paste to the surface. The contact angle of the coatings in distilled water is 68°–85°. This approach is promising for application of Ta-containing coatings on titanium implants and stents for increasing their corrosion resistance, chemical inertness, and biocompatibility.
