Latest Patents

Leonella holds 3 patents related to thermal barrier coatings. One of her latest patents is titled "Thermal barrier coating and process therefor." This invention describes a thermal barrier coating (TBC) made from a thermal-insulating material that includes yttria-stabilized zirconia (YSZ) alloyed with at least a third oxide. The TBC is designed to contain elemental carbon and may also include carbides or a carbon-containing gas formed from the thermal decomposition of carbon. This innovative coating is characterized by lower density and thermal conductivity, high-temperature stability, and improved mechanical properties.

Another notable patent is "Thermally-stabilized thermal barrier coating." This invention outlines a TBC characterized by a stabilized microstructure that resists grain growth, sintering, and pore coarsening during high-temperature excursions. The TBC incorporates elemental carbon and/or a carbon-containing gas to increase initial porosity and form additional fine closed porosity during high-temperature exposures. The methods described in this patent involve incorporating elemental carbon precipitates or directly incorporating an insoluble gas into the TBC microstructure.
