  • Patent number: 10913856
    Abstract: A range of processes is described herein for the preparation of a range of gold nanoparticle (Au NP) ceramic glazes with traditional firing methods that represents significant efficiency and ecological advancements over existing methods and allows for the replacement of commercial ceramic colorant methods, while retaining the costly equipment and firing methods already used. The process allows for ceramic surface color while breaking standards for minimal amounts of transition metal colorant used. The nanoparticle-based glazes described here add new colors to the known ceramic surface palette and offers greater consumer safety as an alternative to existing coloring processes that use higher concentrations of toxic metal and an increased risk of metal leaching from the final ceramic vessel into its contents (e.g., soil, beverage, food).

  • Patent number: 10868899
    Abstract: A method to provide compressive stress to substrates includes depositing a film on a ceramic substrate at a deposition temperature (Td) to form an article, the film having a difference relative to the ceramic substrate at Td in a coefficient thermal expansion (CTE) of at least 1.0×10?6/K and a difference in a refractive index >0.10. At least a portion of the thickness the film is converted in at least one of composition, phase and microstructure by lowering or raising the temperature from Td to reach a changed temperature (Tc) that is at least 100° C. different from Td. The film converting conditions result in the converted film portion providing a difference in refractive index at the Tc between the converted film and the ceramic substrate of ?|0.10|. The temperature of the article is then lowered to room temperature.

  • Patent number: 10852680
    Abstract: There is provided a method and apparatus for preparing a print substrate. A surface resistivity of a print substrate comprising a conductive layer is determined. The determined surface resistivity is compared to a print range having a lower threshold value for the surface resistivity of the print substrate and an upper threshold value for the surface resistivity of the print substrate. If the determined resistivity of the print substrate is outside the print range, a surface modification is selected to adjust the determined surface resistivity of the print substrate to fall within the print range. The selected surface modification is applied to the top layer of the print substrate.

    Abstract: Methods are provided for forming high temperature coating over ceramic components, such as ceramic turbomachine components. In various embodiments, the method includes the step or process of at least partially filling a reactor vessel with a reaction solution containing a solution-borne rare earth cation source. A silicon-containing surface region of a ceramic component is submerged in the reaction solution, and a solvothermal growth process is carried-out. During the solvothermal growth process, the reaction solution is subject to elevated temperature and pressure conditions within the reactor vessel in the presence of a silicate anion source, which reacts with the solution-borne rare earth cation source to grow a rare earth silicate layer over the silicon-containing surface region of the ceramic component.
