The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Sol-gel preparation and characterization of corundum based ceramic oxidation protection coatingsDressler, Martin 23 July 2009 (has links) (PDF)
The Ni-base superalloy, IN-718, has been coated with alumina sols. Coated surfaces, carrying alumina layers having thicknesses between 0.6 μm and 3.6 μm show a significantly reduced oxidation rate when compared with uncoated reference surfaces, even if heating temperature is increased up to 900 °C and heating time is extended to 800 h. Alumina layers were prepared via sol-gel processing using a modified Yoldas procedure to obtain alumina sols. No change in rheological sol behavior was observed for more than 1 year of aging under static conditions at room temperature. Depending on pH value, modified Yoldas sols contain a manifold of Al species, among them Al13 polycations. Thermal evolution of sol derived alumina powders depends on Al speciation of parent sols. Depending on sol composition, both gamma-Al2O3 and eta-Al2O3 occur as intermediate transition aluminas. Phase composition and gas phase velocity influence oxygen permeability of thin layers prepared with modified Yoldas sols.

Flammgespritzte Schichten im System Al2O3-TiO2-ZrO2Kratschmer, Tim 17 January 2011 (has links) (PDF)
Beim Flammspritzen von Mischungen im System Al2O3-TiO2-ZrO2 treten vielfältige Effekte auf. Es kommt z.B. zur Ausbildung eines amorphen Anteils, der in Form von amorphen Sublamellen, dem primären amorphen Anteil, und in dendritisch geprägten Bereichen, dem sekundären amorphen Anteil im Gefüge vorliegt. Dieser beeinflusst die mechanischen Eigenschaften deutlich. Bei einer Temperaturbehandlung entstehende Ausscheidungen von ZrO2 oder verschiedenen Zirkoniumtitanaten beeinflussen die mechanischen Eigenschaften ebenfalls signifikant.
